Clearing SmartApp Cache 
SmartApp stores its cache separately from chats and contacts. Clearing it does not close the session and does not delete the conversation. It helps if the data in SmartApp has not updated or SmartApp is running with an error.
- Open the SmartApp.
- Click the ellipsis button and choose Clear cache.
SmartApp Doesn't Open on Android
- Open Settings > SmartApps Cache.
- Clear the cache for the SmartApp you want or select Clear All.
Didn't help — collect the SmartApp log and contact Support.
Clearing Home Screen Cache
- In the mobile app: press and hold the “Home” button and choose Clear cache.
- In the web and desktop app: click the three-dot button at the top of the main page panel and select Clear cache.
“Update” and “Clear Cache” Screens in Web/Desktop
The company server may require you to update the app or clear local data for compatibility. These screens are enabled by the administrator.
| Screen | What happens | Re-login required? |
|---|---|---|
| Update (no clear) | The app is being updated; the session is preserved. | No |
| Update / Clear Cache (with data clear) | Local data is deleted, and the session ends. | Yes |
You can also reload the app yourself: Ctrl+R (Mac: Cmd+R) or Settings > About > Clear All. In the web app, Ctrl+R immediately reloads the page. In the desktop app, as well as after Clear All, a selection window appears: the Reload button restarts the app, while Clear and reload also reloads data from the server. The session is preserved in all cases.
Clearing Cache from Server
An administrator can reload the chats and contacts cache on user devices in the administrator panel. The buttons are described in the administrator guide.
For Administrators: When to Clear Cache From the Server
- This is a last resort: use it if restarting the application didn't help and support has reviewed the logs.
- Clear chats, Clear contacts, and Clear cache reload data from the server; the session is preserved.
- Clear all ends the session: the user will have to sign in again. Click only if you can't avoid signing out.
