I added the OneSignal integration. All but one of the tags are coming through reliably.
The ‘active_subscription’ tag (which for some reason was initially blank and I later filled in on the integration page with its default value of ‘active_subscription’) is present in some integration events, but not for others.
I seem to get a `true` value for `TRIAL_STARTED` events, and a `false` value for `EXPIRATION` events. But nothing for example for `CANCELLATION`.
Can someone clarify the intended behaviour here?
