When experiencing some unexpected behavior with the app, you can try several steps to help you troubleshoot an issue.
Restart the device
The first step to try is to close the app completely, reboot your device and then re-open the app.
Reset local data
This step of clearing your cache on the desktop app has proven to be helpful on many occasions.
To do that, you'll need to open the app, go to the "Help" menu, and use the "Reset local data" option. Once done, completely close the app and try to re-launch it.
Reinstall the app
If that doesn’t help, make sure you use the latest version.
