"It turns out there is a downside to buying a tablet with (at least) a nine year old operating system whose manufacturer hasn’t provided any updates for it in that time.

We updated the security certificate on our servers last week, as all sites do every few months to a year. In short, your SkyDemon software is working perfectly, our servers are working perfectly, but your operating system on your tablet no longer knows how to trust some new security certificates so it won’t let the two communicate.

I’m going to see if I can buy a different certificate next week that’ll still be trusted by those old operating systems. If successful, that will buy us an additional year. But it might be a good idea to ask for a new tablet for Christmas."

In what respect does it "not work"?

It appears that a security update has broken Sky Demon on the most prolific Android tablet that people use, the Samsung S2 8.0! This is on Android 7.0 at the max. Those with lower versions have also reported that their Sky Demon is no longer talking to the Sky Demon server. Is there anything that can be done about this, at least for Android 7.0? I've had a look at the tablet security settings for this particular tablet and it appears you can manually load a certificate. Would this be something which could be applied as a workaround? If not, would it be possible to roll back the certificates until a more permanent solution can be found?
