I have had a recurring problem when trying to post photos while on the phone or tablet using the (Android) App.
I get a message hat I do not have permission to post attachments in this forum even when I am signed in. When I go to the PC and sign in it allows me to make the post w/ attachments.
FYI - I have experienced the same problem over on iRV2 lately.
