After scouring through the forum, it seems that this problem may be limited to certain devices or to certain software types. I am currently using Office 365 for my Macbook 12" (2015) model and am running on Mac OS Sierra version 10.12.3 (16D32).
My powerpoint version is:
The problem is that when I type into any text box or title in Powerpoint, the text appears very slowly. Makes it difficult to type quick and fast and the lag is really irritating.
I tried the numerous workarounds here and it doesn't work. From booting in safe mode to closing all other applications and even removing ALL of my startup items, it still is slow when typing.
The only time it doesn't work is when I create a new user account on my Mac and swap to the new account and opening a new powerpoint file, the typing returns to normal.
I hope MS can resolve this issue or at least help pinpoint what the other causes may be.
