Thunkable App screen is black

When I opened the Thunkable app on my iPad the screen is black with a blank gray toolbar at the top?

BTW, I accidentally removed the Thunkable test from TestFlight. How can I get it up and running again?

Thanks,
Phil

I think you can just go back to your email invite to re-install. If not, please fill out the form below:

Get the Thunkable iOS companion (Form)

Restarting the email invite doesn’t work so I’ll fill out another form. Thanks!
