I have been playing the update on my devices. I have a Galaxy Tab S2 (Android 7.0), a Galaxy S8 (Android 9.0), and a Pixel C (Android 8.1). I also have a Chromebook but I have not tried it on that device yet. I plan on doing so soon.
The new update works fine, but on my lower end device (Galaxy Tab S2) it is a bit slow. Mainly it is only slow when tapping on my cards to bring up my card hand. There is a pause of about 1.5 or 2 seconds. Also, after I am viewing my cards and I tap another area on the screen (to close my hand), it is slow responding there as well. It isn't the worse thing in the world, but it is a big difference between the last version to this update. Just thought I would mention it.
