Hey there, thanks for mentioning this issue. If you haven’t already, could you try logging out then back in to see if that resolves the issue?
If that doesn’t work, I would suggest going to Settings -> Debug -> Delete Local Database. This will clear all accounts on your device. Restart Thunder after clearing the database and try to login again.
If all of that doesn’t work, please submit a new issue on GitHub with more details (Thunder version, screenshots, reproducible steps, etc). Thanks!
