It seems to have been replaced with Chessbase India (not Chessbase Online): https://play.google.com/store/apps/details?id=com.chessbaseindia.app
There is mention of it on chessbase India website: https://chessbase.in/
Coincidentally, Chessbase India was my first attempt (never tried online) but I have never been able to log in! I use my chessbase credentials and it failed. I have just set up a new app account and I'm in. BTW, when choosing user role you must tick your role AND then "Done" from the popup
TBH, I can't remember why I tried to install it in the first place 😊
Is there anyway to get around this issue? I'm trying to re-install Chessbase on my phone but it's saying that I can't anymore as the app was made for an older version of Android. However, I've just had it on my phone and was using it without any issues.
