Push notifications no longer working

Push notifications no longer working

Hi Zoho Team,

I have been running the Zoho mail app on iOS8 with an iphone 6, and after disabling push notifications once I have not been able to successfully re-enable them. 

I have tried:

- signing out, then back in on the app itself
- removing, then re-installing the app
- ending all sessions in the settings section on the desktop UI
- deleting all the API tokens in the settings section on the desktop UI

Upon re-installing I should be prompted by iOS to allow push notifications (which I am not). 

Please help.
