"android one"
Instaled OneCalendar version 3.9.0 on a Alcatel 1B 2021 running Android 10 (Go Edition). When I try to add accounts, I was able to add an Exchange account but unable to add a Google Agenda or a Outlook.com one. When I press Google Agenda the app does not react, same with pressi Microsoft, all other options react fine.
Please help, OneCalendar was fully functional on my former smartphone running Android 9.
