hi,
There could have been an issue with the app at the time when you tried. Pl can you try again now. Also when you get the blank main screen you can try a search and type the name of the app you want, that work at times. There are some chinks in the App Installer / App Store which still need to be fixed. If you tried FDroid and that is also not working this issue could be different. FDroid takes some time to refresh its repositories before the first run.
I didn’t have any problem last week but today applications are being downloaded very slowly in Apps (like 100 ko per minute) even on Wi-Fi and then it suddenly stops.
Is there an issue going on?
There was an issue on the servers with some processes getting stuck and occupying all CPU resources. This got resolved. Closing thread as issue got resolved.
