This is only a mobile app issue. It works fine on the website (web app).
I have a funding plan that shows $2000, but when I try to fund using that plan, it only allocates $1500. There is one envelope for $500 that doesn't show the funding amount. I must enter it manually.
Mvelopes support said "just fund using the website". What!? Just too lazy to fix it? This sounds like a bug that needs to be fixed. But just for grins I decided to list it here as an idea.
