I've linked my Strava account to my Viafit account, but workout info in my Viafit account is not being received by Strava. (FWIW, Viafit appears to be part of Egym.)

Big picture: I have a Matrix R50 stationary bike with an xID (Viafit) username. Workout info (particularly calories burned) is therefore recorded to my Viafit account. Ultimately, I want that data sent to my MyFitnessPal account so my daily diary would have data about calories burned through exercise.

MyFitnessPal does not play well (or at all) with Viafit/Egym, so it was suggested that I find an intermediary service to connect the two. Like an interpreter--one that speaks Viafit and one that speaks MFP. The concept: The interpreter gets info from Viafit, and then the interpreter sends that info to MFP.

According to online sources, Strava speaks both Viafit and MFP. I successfully linked my Viafit account to my Strava account. (Strava appears in the Viafit app under "Connected Apps." Slide the switch, which takes you to the Strava login page. Log in, and I'm told that I've successfully connected. I've also checked my Strava account on a web browser, and in Settings|My Apps, "Egym" appears there, and as I say, Egym is the same as Viafit.)

I've also linked MFP to Strava, doing a similar process in the MFP app. Strava on the web shows, in My Profile, that I'm connected to MFP. 

However, after a bike session, while I see the data in Viafit, nothing goes over to Strava. And as expected, therefore nothing goes over to MFP.

Any suggestions?

Thanks.
