Is there a way to "fix" rough edges on heatmap tile layers for online display?

[BillSchlatter]

I'm currently working on a webmap for display using ArcGIS Online, and I've been asked to include a heat map layer based on the data.  There are too many data points for AGO to render the heatmap efficiently, so I'm trying to create a tile layer in ArcGIS Pro to speed up performance (using Sharing -> Share as Web Layer).  It technically works, but there are display errors along the edges of tiles at some zoom levels.  I've attached a few screenshots of examples.  

I understand that this problem is similar to another question from a while back: How do you fix heat map 'tears' after exporting from ArcGIS Pro?  The key difference is that I want a tiled output result for use on a webmap, so workarounds that involve converting to .jpg don't seem to solve the problem.  

Has anyone else encountered this problem?  And has anyone found a way to make this kind of map display correctly?

Hi Bill.

I'm working on a project, have followed the same scenario you've described. I'm facing the same problem with rough edges and ran out of solutions.

Have you found any workaround?

Thank you

Hi Moataz,

Unfortunately, we never found a workaround.  We ultimately decided to drop the heatmap layer from the project.  It's been nearly a year and a half, I'd hoped they would have improved the tiling algorithm to get around this by now.

Well, I think will have to find other visualization tools other than heat map, thank you Bill for the reply. Appreciate it.
