Found it!

TL;DR:
WooCommerce Upload Files, v53.7, is causing CartBounty event problems.

Long story:

I deactivated ALL plugins except for WooCommerce and CartBounty, and 3 events suddenly appeared in the WP event list (cartbounty_notification_sendout_hook, cartbounty_sync_hook, cartbounty_remove_empty_carts_hook). Also, the banner disappeared. I didn’t even have to deactivate/reactivate CartBounty.

I did, just in case, and the events were still there.
Then I started re-activating all plugins one by one, starting with Avada related, then WC related, then payment, etc. I ended up re-activating cache, then Yoast, then Secupress.

The 3 events were still there. So I couldn’t find the culprit.

I forced running the jobs (wp cron event run --due-now). The 3 cartbounty events executed and they re-appeared as pending events for the next minutes/hours, so all fine.

Trying to find the problem I then deactivated/reactivated CartBounty again, and voilà! The banner re-appeared!

So…. I repeated the tests but deactivating/reactivating CartBounty after activating each of the other plugins. Then found that CartBounty error banner shows after reactivating it only after WooCommerce Upload Files was active.

I kept WooCommerce Upload Files deactivated while finished the test with the rest of the plugins. No other seems to be causing problems.

Yes it does persist. I tried that a couple of times before posting here. I also tried it again right now just in case. No change.

Should those hooks cartbounty_notification_sendout_hook, cartbounty_sync_hook always be present? Or do they depend on the plugin settings?
I mean, maybe they’re not present because we don’t have that specific setting enabled. So the problem would be the misleading notification banner, and not the cron events themselves.

Just guessing… xD

Following your test, I just re-enabled native WP cron on the site, and made sure events are being run on requests to the site. Then tried again disabling/enabling the plugin, but the problem still persists (the banner shows, and I don’t see those events in the event list)

I’m sorry to say we changed plugins from SuperPWA to PWA for WP (1.7.27), and now the issue is gone.

AMP plugin was complaining about register-sw.js being invalid, and is was being removed.

Hope it helps someone else.
