I've got exactly the same problem: level iii upgrade, but in the app (android) it doesn't show the extra effect options anymore, while yesterday this worked fine.
If it could help technical support: I think the last update that I did to my settings, was raising the number of banks from 10 to 20 in the "settings". After that, I think my effect were gone in the app.
The PC app does still show them correctly.
When I load a rig with tier 2 efx in bank 9, everything seems ok on the RM on my desktop.
When I open that same rig in IOS RM, the tier2 efx is removed and replaced by a green scream.
