Eufy Security App multiple user cannot access

I have recently brought the eufy security app, I had installed the hub, outdoor, doorbell, and indoor camera with one Admin user.

I have invited another user for one of my family members and installed the app on the other phone through invitation. In this app every time I have to install the app with new login credentials it works fine.

The next time when I access the app, always displays the error connection timed out, Now again I have to uninstall the app and install and login with the same credentials it works.

Note: I have not changed any user credentials, all the time I have unistall and install each time for this one of the user.
