I have office 365 ProPlus. In Excel I can see functions like Filter, Sequence, Unique, and other dynamic array functions, etc. but for some strange reason, I don't see the LET function. The Intellisence does not recognize LET, furthermore, I get a "#Name?" error. I have the latest version Build # 12527.20988. I searched the internet for this error, but nothing. any help would be great.
