just updated to 15.1.1 and am working on an 80+ page document which I cannot spell check!!!!
Seriously looking online this issue has been occuring for way too long. I'm paying good money for software that does not deliver on simple things like Spell Check?????
Fix please ASAP. I have clients waiting on documents and I dont know what to tell them. My spell check doesn't work???? How professional is that using such Professional software!
