Excel iOS app not autosaving and freezing.

At my workplace this is essentially a full work stoppage. I have tried with small, large, old, and new workbooks. I have tried saving locally, I have done the App Settings > Reset Excel troubleshoot, I have uninstalled and re-installed the app, I've done a software update, I have even now been issued a brand new device, and the saving/hung app issue continues. This is an ongoing issue over the last 11 days at least. This is affecting iOS users globally at the end of a fiscal quarter. This is a major issue and should be publicly addressed. Microsoft should be updating users on progress toward a resolution, at the very least in the App Version notes in the App Store.
