Missing web part from the add a web part group on sub site pages. I deployed web part to the app catalog and CDN. I’m able to use it on the top level of my website without any issues, but I can’t get the option to add the web part to appear on any sub sites. I tried adding the app to the site contents page like I did for the top level and I’m getting the error that:
A different version of this App is already installed with the same version number. You need to delete the app from the site and the site recycle bin to install this version.
Are SPFX apps only usable on the top level? Did I miss a step during the build/deployment process? I can’t seem to find any documentation or others with the same issue (on-premise) in forums. All the forum questions I'm finding are dealing with online which runs a different version of the framework. Here is my set-up:
SharePoint 2016, CDN is pointing to a site assets folder on SharePoint, and package.json...
