Alphabetty 452 doesn't work

Munty

This level won't seem to accept any words. Not just that I can't get credit for making words of a certain length, but it just won't accept ANY valid words.

Playing on the Android version.

I am on Level 372, and it also will not accept any words.  I am playing on the app on my Android phone.  I have quit and restarted the game several times as well as trying many words with varying numbers of letters in each word and using the 3 letter words the game suggested but to no avail.  No words work.
