Is it possible that the device is identified something other than Pixel5a and the app is not compatible with that specific device.Hulu isn't available: "This app is not compatible with your device"
I have seen people complain that with the SNF sometimes Three device is recognized as Nexus or something really old.
Somehow it does not happen to all.
Check your device at Google and see if it sees it correctly?
Perhaps uninstall SNF, reboot, and reinstall.
Just an idea.
Update, somehow I missed the last few responses,
All good then
