Never seen that before. The bot should reply right away and grant access right away. Send me your invoice number in a DM if not. This error is coming from the Digger code- however, it's possible stuff is just out of date because Unity's package manager is completely broken in most versions of Unity and you have to clear the package manager cache before upgrading any asset, otherwise it says you have latest but just gives you an old version. Wonderful bug, with Unity would tell people about it and save everyone time instead of hiding it.
