Gmail extensions mail count is not working

The Gmail inbox feed is recently having issues updating. It is only updating after 2 consecutive and different emails have been marked as unread.

This is the official Gmail inbox atom feed API which is having issues as of May 30th and which many extensions are using: https://developers.google.com/gmail/gmail_inbox_feed

It is affecting all Gmail checking extensions:

  • Google Mail Checker by Google
  • Checker Plus for Gmail by Jason Savard
  • and more...

Note, the same issue can also be reproduced by marking emails as read instead of unread.

Steps to reproduce the problem:

  1. Go to Gmail and mark an email as unread
  2. Click refresh in the "Checker Plus for Gmail" popup window or wait 1 minute in the Google Mail Checker
  3. Go to Gmail and mark another email as unread
  4. Click refresh in the "Checker Plus for Gmail" popup window or wait 1 minute in the Google Mail Checker

The unread mail count is not correctly displaying the number of unread emails with each mark as unread after refreshing. It only working after 2 consecutive mark as unread on different emails.

Are there workarounds or alternatives that do the same thing, or do I need to wait for Google to fix it?
