[iOS] Map markers still visible on top of cluster after zooming out

Thanks for the library, it's really cool, I've noticed a bug with the example code, when you zoom back out the pins still appear. I'd expect the pins to disspear, right?

[JiriHoffmann]

Hmm... That is really odd! I've never seen this issue before and the same thing with the Google Maps issue. I'll try to take a look at it over the next weekend if I have some time.

@JiriHoffmann I've noticed your example is running "react-native-maps": "^0.29.4", while I'm running "react-native-maps": "1.1.0",, will take a look quickly...

[henrymoulton]

Can confirm that your example does work so it's probably a problem on my end dependency wise

[henrymoulton]

I'm running "react-native": "0.66.4", example is "react-native": "0.66.3", so most likely the maps discrepancy.

[JiriHoffmann]

Yeah, that definitely could be it, it seems to be an issue with rerendering on the map rather than the clustering itself

[henrymoulton]

Looked into the release notes since 1.0 and couldn't see a good reason this would happen hmm.

[henrymoulton]

There is some mentions of a new Google Maps renderer but can't obviously this is Apple Maps, any thoughts @JiriHoffmann ?

[henrymoulton]

@JiriHoffmann I've noticed that sometimes with Storybook the clustering is fine and then when I turn off Storybook the map keeps default markers where there were previously clusters.

[henrymoulton]

I do think this is a react-native-maps bug, but unsure how to further debug...

This turned out to be a bug with Reanimated.
