Hey! Thanks for reporting this and sorry for the delay in response.
Unfortunately, its quite difficult to implement local-only notifications because of how restricitve Android is with regards to background tasks. The notifications feature is heavily dependent on the specific OS version that you have (different manufacturers do different things to help with power saving, but as a result, breaks/restricts background tasks from running)
The only thing I can suggest is to turn off battery optimizations for Thunder. After that, disable and re-enable notifications in the settings. If you go to Settings -> Debug, you should also see an option to test out notifications to see if Thunder can trigger them.
If none of that works, please let me know (ideally on Matrix) and I can help troubleshoot further!
Thanks for highlighting that feature, and I’m glad you find it useful! It’s a super simple addition, but one that adds some value to know how active a specific user has been.
If you do have any additional statistics you would like to see, feel free to create a feature request for it on our GitHub.
As a sidenote, I’m a bit concerned about your battery there 😰
