I’m really sorry about this, @winterlinde—this is, unfortunately, a recently-introduced bug that we are working hard on fixing.
Stay tuned for a fix! I do not have a specific ETA on when it will arrive, but it’s hopefully coming in a few short weeks.
In the meantime, for me the stylesheet DOES actually change on the front-end, but the change is just not reflected in the settings panel.
So, for example, if I choose the “Skeleton” stylesheet, and save changes, then in the settings panel it will still just stick to the “Tribe Events” stylesheet option as if I hadn’t changed anything…
BUT, on the front-end of the site itself, the correct Skeleton stylesheet is loaded.
☝️ Do things behave this way for you, too?
Thank you!
George
