Fitbit App doesn't work, It opens with a quick blinking, then closed the app automatically.

The solution is to uninstall the App and reinstall it again. However, It is too annoying. It happens 8 times to me today. 

I am using Fitbit Versa 3 which I just bought it a week ago, Android Huawei P20 Pro, everything my phone and the watch Versa 3 is up-to-date. This is the only problem which I couldn't solve by my research from the internet. If the app has to be reinstalled many times a day, I have to refund it. It's because once I reinstall, everything needs to reset again, it is too annoying. 

Actually, I have an IT background, I have already change the App launch the Fitbit app to manage manually and avoid the phone turn it off the app because of using too much battery, etc...

I wish someone can teach me how to fix it. Thanks in advance
