Me too, I have been having issues for the last two days. The issue seems random; the games will work sometimes, and when I come back later they don't work and vice versa.
I only play on the web using a windows 10 laptop, and a windows 11 desktop. I have no idea if the same issues are happening with any mobile platforms.
This morning, I am having some games say, “something went wrong” — playing on iPad using the app. Ironically, I was able to play WordWipe and got 600 points for doing so, but went to play other reward games and now get that message. Logged out, logged back in, still doing it.
