Azure Notification Hubs - Issues with Tags after FCM Migration

Question

After migrating all our android installations to FcmV1, I'm seeing odd behavior that didn't exist prior to the migration.

I have two subscriptions each with a notification hub and they're exhibiting different behavior when sending template notifications. When I use the tag expression, {Default && attribute:value}, Notification Hub A sends it to both my iOS and Android devices, but the Notification Hub B only sends it to my iOS device.

I've included the difference in the message telemetry below.

Notification Hub A

• I received the notification on iOS and Android
• Target platforms only show apple
• Shows the outcome results for both Apns and FcmV1
  

Notification Hub B

• I received the notification on iOS only
• Target platforms only show apple
• Shows the outcome results for Apns and no attempts for FcmV1

Now here is the kicker: When I change the order of the tags to attribute:value && Default, both notification hubs work as expected with the exception of the telemetry still only showing apple as the target platform.

I would appreciate any ideas on what could be causing this behavior.
