Each Inner Circle activation link and each private invite works only once. An invite usually shows as invalid or already used for one of these reasons:
You already joined. Check your Telegram chat list for the PickBot Inner Circle before asking for a new invite.
The invite was used by someone else, for example because it was forwarded.
The activation link was already used. It will not create a second invite.
The subscription is not active, for example because it was cancelled.
What to do
Search your Telegram chats for PickBot Inner Circle. If it is there, you are already a member.
Check that you are signed in to the Telegram account you used to activate.
If you still can't get in, contact PickBot Support with the email you used at checkout and your Telegram username. See How to contact PickBot Support.
