I logged in today on my smartphone and tried to do my daily donation.
The problem was that the game kept disconnecting, each time I tried to donate. For about 3 times (until I stopped trying)
Then, I logged in on my PC and was able to donate without any problem
So this seems to be a bug confined to the Android (or smartphone?) version.
Device : Smartphone BQ Aquaris M5, on Android 6.0.1
I’m sorry for the low quality, but I had to record on 480p on my smartphone
