I need to buy 20 users. For evaluation, i downloaded zoho and i created admin user - mubashsher.salim@gmail.com

I registered 5 users

Urvashi.verma@adarshgroups.com
Waseem.jafar@adarshgroups.com 
Jyoti.rawat@adarshgroups.com 
Akanksha.bhatt@adarshgroups.com 
Iram.khan@adarshgroups.com

I have checked my settings, all are active with manager role given. They work perfectly ok on computer.

However they are unable to login to mobile App. It gives error "User_Not_Active". Please activate it on and urgent basis. I need to give demo to my team.
