Agenda not writing in android 7.1 lineage os

[badrow]

The problem is a bit weird because it was working before and suddently it's not working anymore... The problem occurs with a tablet LG-V500. When I add entries in the calendar from the phone, and reset the calendar in the tablet app, in this way the sync works. But when I create an entry from the tablet, it appears in my agenda but does not sync. And if I reboot the tablet, the calendars in decsync are unchecked, and if I check them, the entries I created before does not appear. I wiped cache and dalvik cache and reinstalled the app but I can't find where does the problem come from...

Here are some adb logs, may be it can be useful :

It is indeed a bit weird. Looking at the logs, it looks like the calendar account cannot be created. Can you in the Settings app go to "Accounts" and check whether there is a account "DecSync Calendars"?

I checked, there is no "DecSync Calendar" account. Decsync Contacts is here, working and syncing but not calendar.

Indeed, the calendar account cannot be created. DecSync CC tries to create the account every time you open the app, so it keeps failing. It is also strange that contacts accounts are successfully created. I don't really know how it can fail. Some guesses:

• Can you create calendar accounts with other apps?
• Have you granted DecSync CC all the necessary permissions?
