Calendar events are reverted to original after an update is received

[meetc0]

I am experiencing an issue where existing calendar events that receive an update via an email with .ics attachment. I am not sure at present where the issue originates, the calendar app on my mobile phone, Davx5 sync, or Nextcloud. There are no error messages seen.

My steps to reproduce:
A calendar event is received via email as a .ics attachment
The event is accepted, and added to the local calendar on mobile phone
Event is synchronized with DAVx5 to Nextcloud
An update to the event is received via email as a .ics attachment
The event is updated locally on mobile phone
The event syncs to Nextcloud, and the event is reverted to the content of the original invitation

I submitted this issue previously via davx5.com/support. Debug log is attached to the support ticket #153267

DAVx5 cannot modify ics files as of right now. If you want to modify events from Nextcloud, configure the account correctly as explained here.

Sorry for the inconvenience, or ask again if I have misunderstood something.

Happy new year.
