That's frustrating. My indoor rides are working fine on my free strava account, but I use a computer. They have disemboweled free strava, so it might still be worth paying.
I got similar b.s. from RWGPS support. I even made them a route that would demonstrate the problem I was having and they just told me my problem wasn't worth bothering the devs with. They are too busy trying to become strava. Which might work out for them the way strava is going.
