StripeTerminal.discoverReaders is returning -1 on Android

Platform

• [ ] Web
• [ ] iOS
• [x] Android

Describe the bug I upgraded capacitor from 6 to 7 and then upgraded @capacitor-community/stripe-terminal to 7.2.1 and also added:

stripeterminalCoreVersion = '4.5.0' stripeterminalTapToPayVersion = '4.5.0'

to variables.gradle. I have followed all the steps and everything works great on the browser, and iOS but Android always returns -1 when using StripeTerminal.discoverReaders. I have no idea why this is happening and I'm at a loss.

Expected behavior It should discover readers and not simply return -1

Using Function:

• [ ] Payment Sheet / Payment Flow
• [ ] Apple Pay
• [ ] Google Pay
• [ ] Identity (@capacitor-community/stripe-identity)
• [x] Terminal（@capacitor-community/stripe-terminal）

To add some more context here the issue is that this

const res = await StripeTerminal.discoverReaders({
      type: TerminalConnectTypes.Bluetooth,
      locationId: this.account.integrations.stripe.locationId
})

returns a res.readers on iOS and browser but on Android res returns -1 instantly every time. The only way I can get the readers array returned on Android is with

await StripeTerminal.addListener(
     TerminalEventsEnum.DiscoveredReaders,
     async ({ readers }) => console.log(readers)

But even then it's hit or miss on Android.
