It looks like the title here is coming not from the title and not from anything inside the snapcraft.yaml but seems to be using the summary field in the store?
I’ve reopened this topic as it sounds like the problem is actually a different one. This seems to be gnome-software showing up bad data.
@robert.ancell Hey Robert! We discussed this before… do you have any idea about why the summary might still be showing as a title? This is really not appropriate, and will mess up the store metadata if we keep that way as people will misinterpret what it means.
