Unfortunately, we don't support the zap functionality through the Primal Wallet at this time. We are currently working on implementing this, however in the meantime you will need to connect to an external extension on the browser, like GetAlby.

That's when the problem started. I set up Primal wallet and could zap in browser and via the app.
I am traumatised from using Alby. So complicated. Guides so confusing.
When I uninstalled the extension, I lost the ability to zap sats from my Primal wallet in browser.
It's possible that you were zapping from the alby wallet and not the primal wallet. We've never offered functionality to zap from our wallet on the web. We're working on this though, should be available soon.
