A recent release of the Roon Server software updated the network management software they use and this caused significant issues for a number of systems using older operating software - especially on “appliance” type servers. They apparently assumed that systems would be running reasonably up-to-date versions of system software.
This isn’t a “today” problem, but if they do a similar update on the endpoint systems this could potentially impact systems using, for instance, older versions of Android.
It would be worth Rose checking with Roon whether this might be the case, and plan accordingly, as it might force a move to a newer version of Android, and that’s not something you’d want to do in a rush.
