I just find out that the Expand-on-click works by switching of the Gutenberg plug-in.
My website encounters the same problem since 1-2 days. The Expand-on-click option on Image block simply fails. Is there a setting wrong, or is it maybe caused by the latest update. See: https://www.elasticspace.nl/es-in-depth/groundstate/ and click on equation (GS.1).
I have the same question:
is it possoble after login to redirect to the persons personal page (referred to with his username, e.g. Walter) with
http://www.mydomainname.com/%username% ?
