iOS version fails to record

I have posted earlier regarding an issue with creating custom maps on iOS - viewtopic.php?t=6888
and it seems that my adventure with iOS doesn't end here :)

I'll probably start from the beginning;

I've previously used the Grand Prix version on Android 13, OnePlus 6 T, and although it had some minor flaws, it works.
So today I purchased the Grand Prix version for iOS, since I've upgraded to iPhone 15.
I backed up my data on Android, and imported it on my iPhone.

I went to my local kart track, manually set the start/go point and some 'information' points along the route, it was a real pain, as I described the reason in the topic above, but I failed to record any data. Most likely, because I went on a gokart and put the phone in my pocket (my bad, I've read the instructions and realized that it could be totally my fault).

Ok, fast forward I decide to create a custom autocross track on my android, with a start and finish points at different locations and a few 'information' points and a split along the way. I simply copy exactly the same coordonates for each point and insert them in my iPhone.

I place my iPhone on my dash where I have a solid mount, and my android on the passenger seat.

Both using internal GPS, and then I realize that iPhone recording gets stuck at exactly 1.45 as you can see on the video https://youtu.be/llh_fN1CgEU?si=lWEJ6ZJs5S0lYSP-, a bit later I get the same error I got today at the local track : Current lap had data problems, invalid lap added, corresponding recordings purged. Please Report to the author (screenshot attached). https://imgur.com/a/2o7ILha

Meanwhile, the Android happily continued and you can see towards the end of the video that I have picked up my android phone and it successfully 'completed the lap'.

Please see attached the lap from my iPhone and android.

If there's anything I can help with, please let me know.

Hello,

LapTimer for Android and iOS utilize the exactly same code for trigger detection and data handling, it is just the user interface that is re-implemented by platform. So i case two devices behave different although they use the same settings, it is some GPS data issue or OS setting. Please recheck you have granted all permissions required: Settings app ‣ Apps ‣ LapTimer ‣ Location ‣ While using the App and ‣ Precise Location. In case that's fine, export the 1.45 lap to KML and send it to Harry@gps-laptimer.de

The "Please report to author" is usually coming up in case the timestamps delivered by GPS are inconsistent. So this is about the permissions or some other GPS quality issue again.

I can confirm that the location settings are set correctly on my phone.
Sorry, I've accidentally sent the .kml twice to you via mail :)

No problem but both are empty. This means there is something wrong with the database. This can be the reason for recording interruptions as well as for the error dialog posted.

Please start with chalking your Lap List. Do you see all laps duplicated? This is usually the result from a double restore - which is actually an import. In case you see no duplicates, goto Administration ‣ Databases and run Check Data until it reports zero problems.

There were 2 problems with the DB.
No duplicate laps though.

I will purge the database and start the app from scratch and will give it a go today again
