I just noticed that I can create but not delete or rename Route + Favorite folders in Kurviger Cloud. The small rename/delete window opens but no effect. The small gree floppy symbol for saving also seems to have disappered. My normal browser is Firefox. Tried with Chrome → same.
Is this a web site issue or could it be it a problem on my side?
Firefox cache emptied → no effect
Renaming/deleting of routes within the folders also does not work …
Firefox + Chrome same. I am on Win 10.
Thank you for letting us know. 
We’ll check this asap …
Thanks a lot for reporting this issue, there was a nasty little bug, it should work now. Make sure that you clear your cache (or use Ctrl+Shift+R) to receive this fix ASAP. Sorry for the inconvenience.
Thank you, problem is solved.
Merry Christmas
