Depending on the role assigned, users might not see certain items in the Process drop-down or the side menu. If you cannot see a specific menu item that you should see based on a role, verify that you are assigned the correct role. If you still cannot see the appropriate menu items, work with your System Administrator to ensure that you are assigned the correct roles and permissions. [![Closed](/sites/default/files/tech_comms/mpl/Skins/Default/Stylesheets/Images/transparent.gif)An item I added or edited is not displaying](#)If you are looking for an item you added or for the edits you made to an item, you might not see them right away. A banner message displays that confirms your updates will display shortly. If you want to see the updates, wait a minute or two before refreshing the page, and your updates will be reflected. [![Closed](/sites/default/files/tech_comms/mpl/Skins/Default/Stylesheets/Images/transparent.gif)My OPUS experience is slow in Microsoft Edge](#)Google Chrome provides the most stable and optimized experience for OPUS. If you prefer to use Microsoft Edge, TraceLink recommends updating the browser settings to prevent performance throttling. #### Optimize for Performance To make sure OPUS session stays active in the background during periods of inactivity. 1. Open **Microsoft Edge**. 2. Select the Settings and more icon (...) in the top-right corner. 3. Select Settings. 4. Select System and performance. 5. Select Performance. 6. Locate the Always keep these sites active section. 7. Select Add site. 8. Enter `https://opus.tracelink.com`. 9. Click Add. #### Manage Enhanced Security To make sure the browser's security filters allow the platform's advanced interactive features to run without interruption. 1. Select the Settings and more icon (...) in the top-right corner. 2. Select Settings. 3. Select Privacy, search, and services. 4. Select Security. 5. Select Enhance your security on the web. 6. Select Site preferences for enhanced security. 7. In the Never use enhanced security for these sites section, select Add site. 8. Enter `https://opus.tracelink.com`. 9. Click Add. #### Enable Advanced Process Isolation Enable dedicated OPUS Platform processing to optimize browser memory and resource handling. 1. Open **Microsoft Edge**. 2. In the Microsoft Edge address bar, enter `edge://flags`. 3. Search for **Strict-Origin-Isolation**, and set the flag to Enabled. 4. Search for **Origin-keyed Processes by default**, and set the flag to Enabled. 5. Select Restart to apply the changes. ![](/sites/default/files/tech_comms/mpl/Content/Resources/Images/global_images/note_tip_24x24.png)Restart the browser after completing these steps. If these options are unavailable or disabled, contact the internal IT team to update browser policies. Some settings may appear under different labels in older versions of Microsoft Edge. #### Are these changes safe? These changes are safe: - **Applies only to OPUS** – The updates affect only `https://opus.tracelink.com/`. All other sites remain unchanged. - **Security protections remain active** – Antivirus, firewall, and Microsoft Defender SmartScreen continue to run. - **Improves performance** – Enhanced Security disables Just-In-Time (JIT) compilation, which can reduce performance for OPUS. - **Uses standard browser behavior** – This change restores Microsoft Edge to standard performance mode for a trusted site. ## Help center [![Closed](/sites/default/files/tech_comms/mpl/Skins/Default/Stylesheets/Images/transparent.gif)The API guideline I exported to Excel is incomplete](#)There is a known issue in the documentation where some API guidelines that are exported to Excel via the Download ![](/sites/default/files/tech_comms/mpl/Content/Resources/Images/global_images/icons/icon_download_to_excel_api.png) icon display only a portion of the entire guideline. This issue will be fixed in a future revision. [![Closed](/sites/default/files/tech_comms/mpl/Skins/Default/Stylesheets/Images/transparent.gif)The API example I copied and pasted has invalid formatting](#)There is a known issue in the documentation where the example might have extra spaces or quotation marks added if copied through a Chromium-based browser (e.g. Google Chrome, Microsoft Edge). This issue will be fixed in a future revision. For now, if this problem results in a validation error, either: - Manually copy the example by highlighting the full text, right-clicking, and selecting Copy.or - Use a non-Chromium-based browser (e.g. Apple Safari) to copy the example.
