Hi,
I’ve had this problem before and could not figure out a solution. Murena.io - Imported Calendar cannot be deleted or edited
When starting with murena I imported a Google calendar containing / and : symbols.
Something in the import went wrong so I now have a calendar that cannot be deleted, edited, renamed and so on.
I tried contacting support back then but they couldn’t fix the problem. I ignored the problem for quite some time, but now I get a lot of sync errors with this calendar that I cannot fix (http server error 404). That’s why ignoring this problem doesn’t work any more.
Appreciate any hints of what I can do.
I guess my worst case scenario is to delete my murena account completely and create a new one without this broken calendar import.
