Unable to add app - because forking this repo does not seem to work

[danieltrick]

If I try to follow the instructions here, I run into the problem that the repo cannot be forked:

This is not a temporary problem. Has been like that for several days 😟

Also, I am pretty usre that this is not a problem with my account, as I have forked various other repos without problem.

Now that is an interesting one. Right now I am clueless about the cause.
Thanks for reporting.
