Error updating component
I was trying figure out, where did goes my calendar meeting, why I don't see it on mobile phone.
It seems that after some error inside logs:
Error updating component: Nelze změnit objekt kalendáře: Schází informace o adrese URL ke komponentě. Možná je neúplná nebo poškozená místní mezipaměť, vymažte ji prosím.
(translation calendar object cannot be changed: mising infromation about URL to component. Maybe incomplete or damaged local cache, please remove).
This is nextcloud account and this important warning should be displayed as dialog together with choice: "Ignore" or "Wipe local cache" (red, maybe with warning that data can be lost).
