How to sync RSS from Thunderbird (Win/Linux) to Android?

Question

Android

I’m looking for something, I’m looking, but I haven’t found a way to read the same on a smartphone as on a PC. It's just that there are a lot of readers, but none of them synchronize the list of subscriptions with Thunderbird, downloaded news, and even more so, they don't mark already read news (so as not to choose what they read and what they didn't).
Maybe someone already found a solution?

If your own aggregator is not an option, then you can use Feedly , Innoreader or any other aggregator and pick up feeds from it. Inside one program on different PCs, you can do synchronization on your own by setting the directory with the base of the program to the cloud, or synchronizing via BTSync (I have Vienna synced perfectly between poppies)
