SSO gets stuck after entering domain in SSO

[Rupam]

Got this real weird issue recently, where my friend is using a google pixel mobile and whenever he's trying to login via SSO in Zoom Workplace, it gets stuck at prompt stating "Continue". Neither he's able to click on "I dont know the company domain" nor does he able to click on continue. 

I have seen that this might be default browser issue as per previous threads but I have checked that the deault browser was Google Chrome only. What might be the troubleshooting over here. Please help
