Update Word for Mojave.
It keeps sending me messages it needs to be updated and that I should contact the developer. If your own product tells you it needs updating for compatibility, it might be a sign of sorts.

The notice could be clearer--not everyone knows what "bits" are--but the bottom line is that Apple is dropping support for an obsolete way that applications used to be created. It's happened before and will happen again. All you need to do is upgrade to the newest version of Word.
I keep getting notices that my Word won't be compatible with the new versions that are coming. Something about Bits or whatever. I have always installed updates to Word. What can I do about what seems like impending doom?

I have a current version of Word and Excel and getting the same warnings.
Why does the developer not come up with a solution for this in plain English and tell us all what is going on????
