IOS 11.0.2

IOS 11.0.2

This morning my phone updated to 11.0.2 and since my Zoho Mail will not open.  I have deleted the app, restarted the phone, downloaded and reinstalled three times now.

When the fresh app is installed, I get through the login and verification screens but when time comes to load the inbox, the app crashes and closes.  Any thoughts on a fix?

My wife is running IOS 11.0.1 and has no troubles with her Zoho Mail.
Thanks in advance
