Been a nightmare – Ivanti Mobile@Work™ Client Review

Had to load this on personal phone for company emails. I do not work there anymore and although I have deleted this from my phone the app is still controlling everything. How does it control everything when it has been deleted? Their tech is not very helpful because I do not know some pin from the company I no longer work at nor have access to their email system.
