Amazfit Watch faces

If I start the walking activity and then (for some reason) pause, it is impossible to resume. Whenever I press "Resume" the face shifts to the walking activity but then immediately goes back (within 1s) to the pause face automatically. The only workaround I found is to save the activity and then start a new one. This is a really annoying bug!

This only seems to be happening with the walking activity. All the other works as expected.

Anyone else experience this bug?

Perhaps you will help reset to factory settings
