My yaml does not specify the architectures to build for, so according to the docs, the snap should get built for all architectures. Indeed, it worked for a while, but but as I look through revisions now, I see that the last build for i386 and armhf was on 2019-05-16.
I can’t find any announcement about those architectures getting deprecated, and the yaml hasn’t changed since March. So what gives? What should I do to re-enable those two architectures?
