Cloud save between PC and android? (Solved!)

SOLVED!

So after 2 days of exchange with bugbyte support (thanks guys!) an error with special characters in the password reset function was fixed and also we were able to figure out that the base problem was on my own cellphone being unable to connect to the cloud service.

Symptoms:
- Internet via WiFi, connected and stable
- Cloud login not possible, no matter what I did

Fix:
- Restarted the mobile phone properly (this didn't work before or alone, but important for a clear cache)
- Switched on airplane mode, wait for 10 seconds, switch it off again (like a reset for your connection)
- Disable battery saving mode (can affect background data transfer)

And suddenly, I was able to login and access the progress I had uploaded from my PC client and download it to my Android device.

I hope this will help someone down the road.
