Sounds more like an app issue. Because it's definitely available on MP. I've gotten several MPs for Indy since MP was introduced (and several multi experience passes since Indy often goes down during my windows, lol).
I can't actually check all the way to pull a MP since I'm about 400 miles away (and thus no way I can scan in to the parks to activate my MP), but I just opened my app and I see wait times, distributing FP times, and "get FP with MP" option.
You mentioned it wasn't even showing wait times. But since it is, maybe it's fixed now? Make sure your app is 100% up to date too.
