Google authenticate not working on Ipad

Google authenticate not working on Ipad

Here is the situation: This is a Zoho Creator with Google apps setup I have a Zoho Creator form that is embedded on a Google site. The form has an upload file field that can upload a file from Google Drive to the ZC database. This works just fine on the MacBook Air On the Ipad however the Google Authentication periodically just hangs. ....are there any solutions to this? I have been unable to get any useful answer from Zoho support.
