I have the VIP app installed for my laptop.
(but havent used it over a month)
May be its a glitch with settings.
1) Can you see if there is an alternate option to login on the web page where you enter the code received via mobile.
I dont know whether reinstalling VIP will change your credential ID.
2)Re-enter the cred id and instant code.
3)Try toggling the 2FA option Off and On.
4)Make sure to set the default 2FA option as VIP app.
5)Make sure you havent set 'remember me' / 'stay signed in'.
6)Use another browser or system and check if its working.
That may help.
