First of all: "the new version of LS" is not a clear description, because tomorrow the version that was "new" yesterday might be old already. So always copy the full version number (you can find this at the bottom right of your installation) here.
without be able to edit anything (bold, italic, underline, etc.).
You are still able to do that, but you need to put the html code.
There are different options of for the editor that you can choose in the global settings (if you have access):
- WYSYWIG Editor always on
- WYSYWIG Editor always off
- WYSYWIG Editor can be chosen (your case).
To me it looks like your editor is blocked by a firewall or something. Try to switch to always on and see what happens.
There was a time where the editor took a long time until it appeared, but this should have been solved by now. I can't remember what the problema was back then.
