Command F very flaky (still)

If I type command F in my document, I get a Find box at the bottom of the screen. If I type a word in there and press > it says the word isn’t found. If I type enter, the word is found.

HOWEVER, If with the word highlighted, I type Command F again, the screen flashes and the find box does not come up. If I clear the highlight by touching elsewhere in the document, type command-F, the box does not come up.

Exit doc back to projects, reopen, Command F again opens the find box, Again once it has found something, it never opens again.

iPadOS 13.4.1. I don’t know how to get the Scrivener version but I’m sure I’m current.

Thanks …
