By logging into the app, you access the Firestore to upload certain data and calculate various parameters. These same functions are executed after completing actions in the app. This works on IOS devices, Chrome and Safari for desktop, but on Android devices, it doesn't access certain values properly, so the graphs that show the data load everything to 0. No error is displayed on the console and I don't know what it could be related to.
I think it may be related to the CPU on Android devices going into a 'sleep' state to save battery life and causing certain functions to not run properly. I don't know if this state can be avoided and always remain active. On iOS devices, in Safari and Chrome on desktop, everything works perfectly.
