BUG with copying app that someone else created

My app’s URL: wsunb.glideapp.io

hi Glide team @Mark and @Jason

I’ve created a challenge in my facebook community where we did a rolling appthat I started and then move to another memebr which continue the development and then to another and so on until it return to me as the last developer to close the app but I can’t copy it to my account (and ?I tried 2 different glide accounts).
I close the browser and PC and reopen and still can’t copy.

appreciate the help.
