Personal best syncing between devices

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.

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

Still no solution this?
