At one point, I think this code was getting lucky and causing all annotations to be redrawn, including view-backed annotations. But we should add something explicit here to update the annotation views.

Actually, I’m seeing a somewhat different bug. The iosapp demo application is configured so that tapping on an annotation’s callout view changes the annotation’s coordinates to the screen center. But if I remove the (otherwise unused) implementation of
-[MGLMapViewDelegate imageForAnnotation:], when tapping a view-backed annotation’s callout, an annotation image (with the default red pin image) also appears at the screen center in addition to the annotation view:[ios] Made annotation view position animatable

#5245 would fix this issue for sure by introducing an explicit update of the annotation view in response to the KVO change notification.

Fixed in #5550, which will be in v3.3.0-beta.3 shortly.

I tested on version 3.3.3, no change. The marker position are updated immediately only if to move the map, or after few seconds

That sounds similar to the issue described in #5755 (comment).

@Gerz-inc Could you provide the sample code for the animated car movement animation as I am unable to achieve the same results for my project?
Thanks
