I think this may be related to the Tesla update 2023.12.5. I updated to this a few days ago and I started to get Teslogic messages saying something like "Teslogic App not receiving data from canbus" or "Phone Bluetooth performance is too slow". I am pretty sure this wasn't happening when I was on 2023.12.1.1, which I updated to about 2 weeks ago I think. I haven't been able to work out how to reproduce this at will, but it seems to have something to do with having the app open but not having pressed the brake pedal. In any case everything seems to work OK in the app despite the message and they don't seem to reappear for the rest of the drive. However, I did notice that the Teslogic battery charge percentage is always 1 or 2 % MORE than the Tesla displayed value. It varies, sometimes it is 1% more for the whole trip, or 2% more for the whole trip or starts at 2% more and drops to 1% more (rounding perhaps?) I am less sure whether this only happened since I started getting the messages (after 2023.12.5) but I don't recall seeing it before.
