As described at Is it possible to drop an unsupported architecture from the store?, there is a bug in the snap store that prevents people from deleting snaps for an architecture once they have been pushed to the snap store.
We briefly supported i386 when initially creating our snaps, however, we dropped support for it when we switched to core20. The presence of the i386 snap results in users who try to install our snap on that architecture being told they can install it from the edge channel which has been regularly confusing people and is something they should not do since our i386 snaps are not seeing updates.
While we wait for the snap store bug to be fixed, is there any way you all can help us remove all i386 snaps for Certbot? Is this something you all can do manually?
