BT Sport - Won't Run Unless You Update Google Play Services

BT Sport is complaining it wants the Google Play Services updated.

Here's the app on Play Store; (It is suppose to be a Paid App but there are versions online)
https://play.google.com/store/apps/details?id=com.bt.btsport&hl=en

My Specs:

OnePlus 5T
OxygenOS 5.1.7 - Oreo 8.1.0
GmsCore-v0.2.6.13280.apk - Installed to /system/priv-app/GmsCore
Services Framework Proxy v0.1.0 - installed to /system/app/GsfProxy
FakeStore-v0.0.2 - Installed to /system/priv-app/FakeStore

Before installing FakeStore I had the Play Store installed, with a Google Account also active in the device, which I had downloaded an app through the Play Store, so I know the Google Account and Play Store work properly with microG installed.

After I installed BT Sport and tried to run it, I received a popup message telling me to update the Google Play Services. I know this has been an issue in the past, typically resolved by either installing GmsCore to /priv-app which I have already done, or updating to the latest version of GmsCore which I have the latest.

So at this point I'm assuming microG isn't supporting this app. I hope this issue can be resolved to get BT Sport working with microG?

Thanks
