Do you have dedicated pages for each layer?
The only sure fire way I have found to make sure layers are available is to duplicate my “cruise” page on the WPT view. (Could be APT or TSK as well)
Set each page up with a layer you want cached.
Convergence, cu cloudbase, wave params, etc…
Then you can switch the layer on your primary cruise page to any of those.
It’s not a great user experience. It really should be a list of checked layers that you set up on a Skysight page. But that hasn’t been implemented yet, so I use the duplicate pages hack.
