Just FYI, I have 9.6.29.331894.apk in the file you shared, without any BETA mention.
Interesting and confirmed! The MULTI included the BETA, the 1920 x 1080 (haven't looked in the others) includes a later dated, and confirmed with different hash APK for that build. I'll have to try it with my resolution and see if there's no problem.
Thanks!
