Is this a non-US app? The only reference I can find to 'NFL Gamepass' is this. However after going to the NFL Gamepass site, their mobile links to Microsoft Store, App Store and Play Store all redirect back to the Gamepass site. Somethings up from the NFL side of things, might want to reach out to them if this is a site you pay for.
On the flip side, XDA does have apks posted but I'm not sure how recent they are. I'm shocked APK Mirror doesn't honestly. I'm wondering if this is being bundled into the standard NFL app?
Yeah I might be wrong about the technical details but that's the only way I got it to work. Here's the direct link to the app after you turn on the vpn. You can open it with play store just can't search for it.
