Training plan problem since 5.30 update

Hello,

my fenix 5s has been updated from 4.1 to 5.3 last days.
Now I have a problem with my trainning plan scheduled.
Before, all my plan was on the watch, but today when I started my run, the watch said me to download the training plan from garmin connect . The plan seems erases from the watch.
The problem is that I can't dowaload it again. When I sync the watch with garmin connect, nothing happens.

Does anyone have similair problems ?

Thks
