Run Zwift Pod (milestone)

Hi everyone Ive been running in Zwift for almost 2 months, I really like it, but to be honest zwift speed is always different from ny garmin 245 and my treadmill (horizon t 202) so I decided to buy run zwift pod, todas was mu first run with that, I calibrated and the pace and the speed was accuratte until last 2km that I speed up, you know why happened that? And my other question is why the milestone app is no longer available? IOS notice that is not available for my country (Mexico) and Android dont have it…
Do you know where can I get all the metrics that Milestonepod display in its app?
