By all accounts ( and threads on this forum) , Zwift dont really make enough effort to ensure support for Apple devices either .
Zwift basically seem to me anyway to be either deliberately ( or more likely accidently ) letting this come about because they have diverted all effort ,energy and investment to creating there zwift hardware platform ( bike). .
The fact Zwift are creating a situation of broken (or very limited) support for wide open access concerns me as I can see it making it very easy step for executive decision being made to only support there own kit. Zwift clearly are unable to support the current situation so something has to give and I doubt it will be the Zwift bike folly , too much investor capital ploughed into it .
