Hi! I'm glad to hear that! Regarding PPA etc I can't say for sure since I don't lead the app team and don't want to interrupt their work day. I'll relay your comment though. I hope that's OK.
This is great to see. I highly recommend your team look into it. Setting up a PPA (or even just your own APT repo on S3) is extremely simple and is a robust way to push out updates. I would be happy to do a few hours of consulting for your team to help get this done.
