Elementor support sent me to the theme developer for answer (you guys must get tired of this).
I created a single post template with Elementor Pro 2.0
I created Right Sidebar with GP Premium and styled it with some additional CSS.
Elementor appears to filter out the CSS if I use their Sidebar widget.
Regardless, I preferred to simply use GP to include the Sidebar as it does on my general Pages.
In the customizer, the Sidebar is enabled for both the Blog and Single Post, so I suspect the issue is Elementor’s code, so they were my first contact regarding this.
I’m thinking this is an Elementor issue because I can solve the problem using Anywhere Elementor.
My issue is that I want to use a sidebar styled by the GP theme with post and archive templates created with Elementor. I was hoping you might have a work around.
As of 40 minutes ago, Elementor crashed the site, so you must have just seen it. Hopefully I can try again tomorrow.
Yes, thanks for the followup. I’m using Anywhere Elementor instead of Elementor Pro 2.0 to create the single posts. I guess that’s the solution until Elementor fixes the problem and stops blaming the theme authors.
