Repacked firmware update for A31 module with WEB UI fixes.

I have the S10+ model. Does the latest firmware support AirPlay 2?

How do you update firmware? I have a up2stream amp 2.1 that is running 4.2 firmware. Has no webpage, the update utility just keeps closing, and I dont even have the right file. The firmware downloads section of arylic is dead and not working, no files are attached?
