I would like to file an issue for a bug, but it seems that is not possible as a free user. Please point me to where I would normally send this. All normal channels for support seem to be blocked. Thus I post it here that you can see it, might be useful for your paying customers as well. When it reached your devs feel free to delete it here in the community
What is happening: No content can be edited, all fields are locked. Sometimes the banner appears:
It appears that you aren’t connected to internet at the moment. The fields are temporarily locked so that you won’t lose any important changes.
We are definitely connected to the internet, everything else works. I was able to reproduce on multiple computers in multiple browsers. Sometimes, after a lot of re-loading we can save things, but only very sporadically.
I hope this helps you get this fixed!
