Supplement. I couldn't reproduce the disappearance of the cursor, but I can't move the cursor to another location like in the video.

When Select / Select All / Paste is displayed, tap another position.

I will report.

I have confirmed that Textastic 9.4.2 and iPad OS 14.0.1 have no problems.

It's working comfortably now. Thank you!

I use it conveniently. Thank you!

I updated Textastic to 9.4 today, but when I'm editing a text file containing Japanese, if I press the cursor keys up or down several times in a row, it jumps to the top or bottom of the file. I will.
