Can't update?

What's the latest version for ONN 4K android? I tried updating in Playstore, it didn't indicate it completed but the update button was gone. Oddly I can't open it from within Playstore . Show cancel, uninstall and open, but open can't be selected. I can still open Debrid Stream via Projectivy launcher screen. It shows very 2.1.0, build 70. Is there an APK somewhere I can get and update?
