Hi @James Nolet? ,
This release 12.2 S02 of Spectrum Spatial Analyst improves map load time in two cases :
1. Where a user browses to Analyst and then logs in to see the map, and
2. When switching map configurations within Analyst.
The improvement is most noticeable when using a modern browser such as Chrome
or Firefox.
I suggest you to install this patch. Instructions are into the Release Notes here attached.
Yes, the SSA roadmap says the next release will be out at the end of November.
