My Android phone doesn't connect to my server with a HID profile

I've been using my Android phone as a mouse and keyboard to my Ubuntu server (originally running 20.04LTS). At some point, after an update, the app I use no longer worked - it just sits there saying "Connectiing..". I searched but found no solution and then gave up trying but now it's becoming a bit of a pain again so I'm hoping for some insight.

I was hoping updating to 22.04LTS would fix this but it doesn't. Weirdly, the phone does connect (and always did) but not with the necessary HID profile. The phone is a Pixel 6a (but a Pixel 3a had the same problem).

bluetoothctl reports the following (you can see HID is missing):

UUID: Generic Access Profile    (********-****-****-****-************)
UUID: Generic Attribute Profile (********-****-****-****-************)

Anyone got any ideas as to why this might be happening?

Thanks

Upgrading a system with issues will never fix a problem. All that will happen is the issue carries over and may be worse.

Not sure I agree with that statement. An upgrade broke it, and new drivers in an OS upgrade could fix it. Not in this case though...

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
