Hey,
I am using the RaceChrono Pro on my old phone a Xiaomi Mi9T Pro using a custom ROM called EvolutionX, I'm not using the stock OS anymore as it don't get system updates anymore. Whenever I tried to open the app I was getting a "Storage not mounted" message and it was prompting me to cancel or retry.
I took a look on the logcat and I saw this line:
"ContextImpl: Failed to ensure /storage/emulated/0/Android/data/com.racechrono.pro/cache: android.os.ServiceSpecificException: (code -1)"
so I quickly drop into the adb shell and run the following to creating the directory:
"mkdir -p /storage/emulated/0/Android/data/com.racechrono.pro/cache" -> For the Pro
"mkdir -p /storage/emulated/0/Android/data/com.racechrono.app/cache" -> For the Free version
And after that everything was working fine, so I just wanted to leave this here, so if more people have the same problem could possibly find a fix for the problem
Thanks,
