I have an active developer account and it's been 10 days since I asked for access to TestFlight and still nothing, I would like to use the Shortcuts application but I was not able to access .... What should I do ?

Just wait. They will release another bunch of invitations soon. Prolly when a new version of Shortcuts is available on TestFlight.

Same thing for me...

I have not received the mail neither. And the request has been optioned for about a week. But all we can do is wait.

I asked a month ago. No response. We are deemed wanting.... :-)

Same here...still waiting 😒
