A family of Microsoft word processing software products for creating web, email, and print documents.
Hello,
I had the same issue! Super annoying. But I just found a workaround.
Apologies if this has already been shared and I did not see it.
If you customize the quick access toolbar,
then add either "Save As", "Save as Another File Type", or "Save As Other Format", when you click any of them it will open the legacy version of saving.
