What I’m trying to do

Since the last update i have problems with images. I cannot see the </> sign only the zoom button. Also it is super hard do get into the line code. It works with the enter method but not with the mouse. Also whenever i click onto an image the zoom doesnt work. Its simply not appearing in fullscreen. I also found out that the zoom is only working in reading mode but not in the editing mode. I is also not possible to grab that little corner to resize the images because than it jumps into the zoom mode that isnt working.

Things I have tried

I disabled all plugins and tried the same things without success. In the pictures all plugins are disabled and there are no css snippets working. What worked is creating a new vault. I put a Screenshot in there and it seems to work… really strange

Did anyone experience sth similar and is there a solution?

This is how it looks when i click onto an image to make it zoom

Cant grab that resizing icon in the lower corner

Ok found the solution - i also had to update the minimal theme inside the appearance menu. Didnt know that and only updated the extension.
