>  3. Please see my corresponding comment at the end!
>  4. CREATE NEW recurring event e.g. bi-weekly with no end date on Wednesday, starting on 3rd of February 2021 and wait until event is updated on the server and visible on the mobile device

> Outcome (BUG identification):
> In TB
> Expected outcome: individual description "hello world second" DOESN'T appear in spezific calender event on 20th of February
> Actual outcome DEVIATES from expected outcome in the way that it isn't displayed anymore

> Conclusion: Changes (SAVING after ADDING descriptions) are successfully transferred to the server. After the synchronizing action the content of the description isn't displayed in thunderbird anymore, however the change is correct and available on the server and also correctly displayed on the mobile device.

I was able to reproduce this after some fiddling but it seems like the synchronization takes place if you restart Thunderbird.
