Limit of 3 KMZ Popups

[GeoffroyRicher-Lalonde]

Clicking on overlapping KMZ polygons, there seems to be a limit of 3 popups that can be shown in the popup window. Is this limit by design? Could it be increased?

Thank you!

Yes, this limit is by design and was introduced to improve popup loading performance. We found that when too many popup requests are triggered simultaneously, it can lead to noticeably longer loading times. To avoid this, we applied a cap on the number of popups displayed at once.

Could you share more details about the behavior or user experience you’re hoping to achieve? This would help us better understand whether an adjustment is needed.

Our use case involves aerial imagery footprints. We use KMZ polygons in different colors to represent the imagery footprint for each year. If more than three years are available, a user might miss one if they only rely on the popup.
