1. Select old sensor from Bluetooth list.

3. Press “+” to add new sensor
4. NFC scan
5. App crash
6. Quit app from switcher
7. Relaunch app
8. Press “+” in Bluetooth tab
9. NFC scan
10. Successful connection

Crash re-creatable on sensor disconnect and reconnect also. Does not have to be new sensor

I can confirm this. I didn't have time until now to check how to make it reproducible. Thanks @OliNix for the reproduction steps.

We knew about this crash when we released 4.11.0. It was even written in the post about the release notes post in Facebook so that people knew it would happen. It only happens the first time, then it is fine.

We considered it better to just let the app crash the first time, then to not release and not fix the scan problems some users were having.

The crash is caused by the numberOfSections issue (which has always existed), now it just happens more since we are refreshing the table more often due to the new workflow.

I did note this, but could not see an open issue so it could be tracked
