Heat Map layer overlay issue with ArcGIS Online

[AlessandroValra]

Don't know if it happened to someone else, but I recently tried the heat map functionality in AGOL to style a point layer in a web map, but the result is always in background with respect to the other layers, although it is the uppermost in the TOC. Any idea why this is happening?

Thank you Luba for taking the time to helping me.

Unfortunately, my data are meant to be updated very frequently, and a tile layer is not the way to go for me.

Anyway, now I know what should I do in order to do it and the limits of this feature as of today.

Thank you for also pointing out the useful links.
