Google is working on a fix for an issue that has caused iPhone users to have problems receiving Google mail on their devices.

Several iPhone users have reported an error message reading “mail service imap.gmail.com is not responding” when they try to access their accounts.

The problem also appears on phones that use Google’s own Android operations system. Google is aware of the problem has stated in its support page, under the POP, IMAP and Sync section, “We are currently working on resolving this issue.”

In the mean time, Google recommends that users sign in to Gmail using the web browser or download the Gmail application.
