Yesterday I went to a track day. As I was opening the app, it displayed a box stating "Package corrupted" as title and with the text "Installation package is corrupted, please reinstall".
I was in a hurry, removed the app, installed again. Same error. I uninstalled, got out of the Beta program (where I was participating due to a previously reported bug, to test the solution) and installed the standard Pro. That worked and I did my tracks and all looked nice.
Today I was going to do the manual sync of my SJCAM videos on the phone, and I see that the standard version was upgraded today. To my dismay, it gives the same error.
I'm very afraid to uninstall as yesterday I lost data from around 15 track days. I have the highlights of them on the overlaid videos but I can't compare anymore. But if I lose my data from yesterday, I'll be really sad...
Today's update was to RaceChronoPro 5.5.2 and I'm a Pro user since 2015, I think
Phone is Elephone S8 with Android 7.1.1
Don't know what additional data I should provide...
