If you use GoodNotes with the tool bar at the bottom instead of at the top (being left handed I find it way more comfortable) it’s impossible to edit any typed text.
When I select some text in order to edit it, the “text edit“ icon is hidden by the keyboard, therefore I’m unable to tap on it. However, if I dismiss the keyboard, the text is not selected anymore, therefore I can’t edit it.
A floating “text edit“ icon that pops up when text is selected could be a solution.
