Would be great to get an answer as to wether this is disabled or if we do have a localised issue (it’s across multiple versions and servers so unlikely?).
the app is supported. But the delayed updates and broken updates via this apps are known since ages and nothing changed up to now (I think we both had that discussion also at least one time on IRC). So the best is to follow my advise:
Don’t use the updater app if you’re relying on working and on-time updates of current versions.
If you follow that and do the manual updates/upgrades you will always have the latest available version and the least danger to get a non-working update/upgrade.
