Worst app ever used.I have been using it for work.One day it asked me to renenter the credentials,and at the end it prompt to add my device in company portal.I have already done it and using this for past few years.so i thought to clear company portal entry and reinstall it.Still no use..now at the end.I am unable to login via mobile.Need to open laptop every time If I want to connect with my team.Very unfortunate and disgusting
