App not showing up in google play for alpha testers with android version 8

Hello everyone,

I uploaded a new update (support for android version 8 Oreo) of my app in google play for alpha testers yesterday. It’s been 24 hours and testers with phones running android version 8 still don’t see the new update. Testers with android version 7 downloaded and tested it after a few minutes that was uploaded.

App’s configurations for Android

minimum sdk version: 19
maximum sdk version: 26
target sdk version: 26
