connect.garmin.com/.../home 這個網頁進去後會短暫出現正常資料但接著就變空白
This page will briefly appear as normal information when you enter it, but then it will become blank
All working from here. Have you tried a different web browser or cleared cache?
I had the same problem some time ago. The reason for this is an outdated browser. The new home page uses some JavaScript functions that the old browser doesn't know.

So update your browser or try another one, as seilogramp has already recommended.
