Cryptogram - Quote Puzzle

Im at Level 739 — around 300 or so all of a sudden, the letter boxes either don’t show up or they stay on the entire time, even when I move to another letter. It’s rather annoying & causes me to take 3 times as long; I either have to do a bit more sleuthing to figure out which word is missing a letter, in order to trigger the end of the level. Also — it would be fantastic if you could make the letter box advance automatically to the next letter, instead of having to constantly tap every time I fill in a letter. That would be great. Other than those things - this is one of the best crypto apps I’ve found — mainly because A. You have dark mode and B. So many levels that I don’t have to pay to play. Cheers

Every level was glitched. It wouldn’t insert letters properly and would stop working.

Gives all the letters except one. You solve for one letter.

Seven games in and unable to enter letters. Waste of time.
