It was a bug, fixed now: <a href="https://github.com/uBlockOrigin/uAssets/issues/11906" rel="nofollow">https://github.com/uBlockOrigin/uAssets/issues/11906</a><p>In uBO settings, under filter lists... purge all caches, then 'update now'
As soon as I disable AdNauseam, it shows the emails. Do you have by chance both uBlock Origin and AdNauseam? That's a configuration recommended against.
I just checked and it doesn't seem to happen here, all emails show up OK when uBlock Origin is enabled. Does the extension offer other controls or filters you can experiment with?
I have several adblockers. It needs manual calibration. Especially creditcards need to be controlled before its send. I have no email from Google, but uBlock Origin.
