Shared calendar events not showing on all devices #5408
Description
Steps to reproduce
Thus far I've not been able to reproduce at command, but it's been driving me nuts and seems random.
Expected behavior
Events in a shared calendar should be shown in both webinterface as well as apps on iOS and Android of the users who have access.
Actual behaviour
So here goes! I share a calendar with my partner and lately we have had some arguing because one of us did not see an appointment and double booked the time. Turns out appointments have not been showing up on all devices. It feels quite random and can happen to any type of appointment (both single and recurring) and is quite rare.
Thus far it only happened to a handful of appointments not showing on mobile devices (and the appointment would always show up on the web interface). Me thinking this was a client side issue, I was checking them one by one (check which devices created the affected appointment once we identified it). But today something really weird happened, an appointment did not show up in the webinterface, but it did on both of our mobile devices. I could also see changes I made to the event in the activity view on the webinterface, but once I clicked the event the editor would keep spinning.
I'll share some screenshots as an example:
After editing the event on my phone (adding an . to the end of the title for both the series and the occurrence, I can see I made changes to the event in the activity screen:
The event shows up on my Android Device in the app OneCalendar and on my Partners iPhone with the default calendar application.
The event however is not vissible in the webinterface:
