In the developer dashboard for the chrome web store, the developer(me) has the ability to add tester accounts to allow limited access to an extension that is published. This feature was working perfectly with all @
gmail.com accounts (so all users are using personal email accounts rather than work accounts). However, recently I've noticed that users that had previously worked from this list, can no longer access the extension web store page. Instead, they get a 404 Not Found page. My own personal "tester" account (meaning NOT the developer account) had access to this extension as well, but now it fails.
Why are my tester accounts getting 404 when attempting to access the Chrome Web Store extension page? This is after I have already accessed the page before and have downloaded the extension weeks ago(I didn't JUST add it and try)..
