Tacx S Flux - software upgrade to version 4.65.4

Hello everyone,

I have a Garmin Tacx S Flux, and unfortunately, I'm having trouble starting my trainer.

After the last update to version 4.65.4, my device stopped working.

Is there a way to revert to the previous system version 4.63.7 on IOS?

Thank you in advance for your support. 

Thank you 

Mateusz
