Some Gmail users have received banner notifications with emails, asking if they wanted to continue receiving messages from the sender.
They said this has been included on all incoming emails, and has continued no matter what the response, Android Police reports.
Google is working on a solution to the problem, which began on Thursday, Android Police says. This Gmail user has not experienced the issue.
The message reportedly reads as follows:
“Do you want to continue receiving messages from this sender? Please give us feedback about this message. We won’t ask you about this sender again, although you can always unsubscribe or mark it as spam in the future.”
