Thank you for your time on the call today. As per our discussion you want to block access to confluence application from mobile browser for all users.
We discussed regarding this and using conditional access policy we can block access to confluence application from mobile browser for all users. However, as you mentioned this is not working because the application uses browser for authentication from mobile apps.
In this case it is not possible to block the application using conditional access policy.
The block has to be set up in the application side itself.
