Keeps losing its certificate – Cisco Jabber Review

I keep getting an error saying the certificate is missing on my device. I have to uninstall the app then reinstall it. It will then let me log into it and function for while or until I close the app then I get the certificate error again and have to go through the uninstall process to get it to function again. I have an iPhone 6S running 11.2.1 software version. Very frustrating! Love it When it’s working.
