Sure, let me break it down for you a bit more conversationally.

So, you’ve got this handy tool, the GA4 Dimensions & Metrics Explorer, which you can access through this link here: https://ga-dev-tools.web.app/ga4/dimensions-metrics-explorer/. What it does is basically help you determine if the metrics and dimensions you’re working with are compatible or not.

When you go to use it, just make sure to have your account and property ID ready because you’ll need to pop them in – there’s an image here that shows you exactly where you’ll need to do that: https://i.stack.imgur.com/S9qFU.png.

Okay, so once you’ve got that sorted, you can start ticking off dimensions and metrics that you’re interested in – there’s a little checkbox next to their names. And, as you’re doing that, you’ll see them get added to your list.

Now, this is the really cool part – if any of the dimensions and metrics are not quite compatible with each other, they’ll gray out. It’s like a real-time compatibility check. So, this might give you a clearer idea of why you’re running into the “[GA4] Data compatibility” error.
