Please provide more details. Which text editing step are you stuck at; are you able to enter text edit mode, or not even that? Is this issue specific to a template/project, or pervasive? A screen recoding would be helpful too.
Thanks for your patience; this should be fixed now. Could you please check again? If you have Express already open in a browser tab, you'll want to refresh it first.
There is a newly introduced bug with text editing that we're actively investigating (My earlier post is still valid, but won't help until the bug is fixed). Thanks for your patience.
