Did NOT fix the problem.

I cleared cache.   I cleared all app data.

I have restarted my phone.   I have deleted the app and then installed the newest version.

Nothing is working.   I can however make product changes on my desktop.  But the problem is i am in the "field" all the time and do everything from my phone.   This has worked for me for 4 years now and all sudden now ot doesn't.   The one weird thing is that if i make a change to a product using my desktop, then I can make changes on my phone to that one single product, but no other products......
