Hourly notifications of calendar sync failed Android & UNABLE to modify calendar events in Evolution

[myviolinsings]

I use Etesync with Evolution on Ubuntu 22.04. I only installed it on my phone, in case I do add something there (mostly add items on pc). But I am getting several notifications a day that Calendar sync failed (error while applying remote entries) and not sure what this means. I have sent the info from Android when I am actually on the phone and can see the log details, but not sure if I get an email or what in response to it, or how long it takes to even know if this is something I have done wrong or a bug. Yesterday, I imported (via the web) all of my google contacts and they show up in the Android app. But I did check to see that a calendar entry from Evolution appeared on the web version and it did not. Here is the debug info from my phone:

--- END DEBUG INFO ---

UPDATE: After about 15 minutes from entering that calendar entry in Evolution, I received the first ever notification on Android that the calendar was updated. Not sure what that means.

UPDATE: Since I posted this 2 weeks ago, I continue to get the notifications on Android but all of my entries entered into Evolution (contacts, calendar, tasks) sync eventually.

UPDATE: **As of 10/19/22, I can no longer modify calendar events in Evolution: "Failed to modify an event in the calendar “myviolinsings@pm.me : Bill's Job & Estimate Schedule”
Cannot modify calendar object: Server error"

And in the browser, not only does it take forever to load my items (didn't used to) I can open to modify item, but clicking "Save" does not save; nothing happens.

On Android: I opened Proton Calendar to see that none of the entries in the calendar which were being synced via Evolution were showing up, as the Android sync obviously has issues, which since i seldom use Android apps, did not notice till now. This needs to be resolved as I do not have access to the calendar that Etesync is supposed to be syncing, nor can I modify any calendar entries via app, web browser or in Evolution: so I am dead in the water.**
