Myself and others have had similar recently.
It’s a bit painful that you get no extra info, and no real way to manage builds via that page. You just have to sit and wait, pretty much.
The only action you can take, is to submit another build, which cancel any current or pending build for the same snap+arch, but that’s it.
I was thinking recently it may actually be better to build and GitHub directly if this becomes too much of a sticking point, and deploy to edge from there. It’s a bit more setup and maintenance, but if you only need x86 and arm, it would do everything needed, and give more insight and controls.
Cheers,
Just
