When initially opening the find tool, it works as intended. Typing into the field works and the buttons (Next, Previous, etc.) all work. However, after changing the Find Options, the buttons grey out and are not usable. I’ve found that closing and reopening the find tool fixes the problem, but it is a bit inconvinent to have to keep doing that when I want to change the Find Option.
Better to post this in the Beta Testing forum, where it will get the proper attention: https://www.literatureandlatte.com/forum/viewforum.php?f=57.
