Ride ons dropping post ride?

I don’t normally pay attention to getting ride-ons, but I noticed something in the companion app notifications recently. After I complete a ride, for a while, I continue to get more ride-ons from people (presumably followers or people I rode with handing them out after the ride is done). That’s cool, but what caught my eye was the count suddenly dropping. I’ll get 3 or 4 notifications with the count going up, then suddenly it drops and it drops by 100+! As a check, today, I took a pic after the TdZ short stage today of the ride end screen with the count I had at the finish to compare.

It’s also inconsistent.

In my activity feed, it shows one number, which I think is correct without the reduction, and the activity itself matches the reduction seen in the notifications. This behavior is matched on the website.
