Personal best syncing between devices

Feature Requests
#1

At the end of a ride you get your 5s, 1min, 5 min and 20 min power compared to your best ever power. When you use different devices / change device it does not match since your personal best does not sync between devices.

Please solve so Personal Best syncs.

#2

Does anyone know if the personal bests can be accessed anywhere else? (my.zwift.com or zwiftpower.com?) or just in the app post ride? Would be nice for a better source to analyze the power
