Hello,
I expect my question is more of a lack of knowledge than any sort of technical issue. I have a Gallery that loads on the front page of my app that previously worked without issue. Over the weekend something seems to have changed and now the gallery no longer loads - stating the operation has failed stating "The number of lookup columns it contains exceeds the lookup column threshhold".
I am not sure what happened as I made no changes to my app in the past several days, and am not sure how to go about fixing it. Any advice on what may have happened or what I need to do?
Reference photos below. Thank you very much for any help.
