@devvv4ever I tried aCalendar+ with no success. Thing of it is, I seem to remember the basic Android calendar working before, when I was only using Nextcloud on my home LAN. Since my website went live it hasn’t worked.
Ok, I understand. Is there any technical information I can pass over to them? I do not have any difficulties with “in deep” and “programmer-like” explanations as I a do backend development myself but never confronted with contact/account management under android.
I will then pass that information over to blackberry to let this issue be fixed.
