LootTheWorld App denying access

Hi mods & gamers, new here/first post-

I recently installed the LootTheWorld mod, and I’ve yet to be able to send any item to game. When I click Send, it replies that it can’t because I haven’t played the game yet, even when I’m logged on and playing (200+ hours so far ingame via Steam, have registered w/Gearbox, use Shift codes routinely without problems, etc).

Everything else re: the app works; I can cam-shoot QR codes, get items into the app inventory, etc, I just can’t send them to my backpack.

Any help with getting it to work would be appreciated, thanks!
