That is a lot more work than when your colleague tells you, please change the hostname or remove /test from the path. It is changes like that from refactoring or development process that are different each time. If this was to be supported, the cache should be cleared of course.
Once every few weeks my calendars from icsdroid disappear and I have to add the URL to the app again. I’ve missed a substansial amount of reminders because of that.
Had never happend to me, and without any further hints I can’t say anything about that. Maybe a 3rd-party app which is messing around with calendars?
I use DAVDroid and OpenTasks on the same device
I can comfirm that my calendar also disappears in the app.
I also use DAVdroid + OpenTasks + ICSdroid on a Oneplus3 with LineageOS 14.1.
I have the same problem. Also have DAVdroid + OpenTasks installed with LineageOS.
Is there any way to do a backup of the calendar settings? I tried using Titanium Backup, but was not able to restore the settings after all calenders disappeared.
