Hi,
in fact, i resolve my problem alone (thanks amazfit support :mad : )

Before all, i backup all my watch (with AmazeBKP_v1.2)
IMPORTANT, put the watch in airplane if you don't want loosing all your sport activity into the watch.

i'll explain what i do:
1. put the watch in airplane
2. try to see if the watch is connected to amazfit app, normally no, because it is in airplane.
3. if you don"t see the watch, go to amazfit app, and remove the watch from your account.
4. log off from amazfit app
5. Remove the app
6. reinstall the app !
7. logon with your account
8. add the watch ! ... now, for adding a watch to amazfit you need a QR Code... but, if you want a QR Code, you need to reset your watch ! nooooooooooooooooo !!!!!
open a cmd, go in a folder where there are adb (personnally i use adb from amazeBKP), and type: adb shell am start -n com.huami.watch.setupwizard/.InitPairQRActivity
9. the watch QR code appear, you can add it in your amazfit account.
10. force synchronize data from the watch (need wifi)
11. wait a few minute

With this step my amazfit app work again, and i retreive my 179 Sport session ! OUF !!!

For your information if you don't put the watch in airplane first, when you will remove the watch from your account, the watch will be reset automatically and you loose all !!!
