This is what support says:
Plugins created during the alpha are now available in the Plugin Marketplace and can be filtered with the new platform compatibility filter in the /plugins and editor plugin marketplace. There is no public release timeline yet for broader mobile plugin support or for mobile-specific templates and component library updates.
Users can still use custom server-side actions from your plugins within native mobile apps, but full mobile plugin development is not yet available.
I hope this answers your query. Please let me know if you have questions or clarifications.
I found this really misleading (deceptive?) - I bought this plugin to use it in a Bubble Mobile app, but it is not accessible in the Mobile Builder. Why are plugins being listed as “Web & Native Mobile” when they are NOT accessible in the Mobile builder?
Hi Richard,
This is Bubble’s doing I’m afraid. Plugins that have a visual element are not available in the native mobile builder right now, this is my understanding anyway. If any plugin has any server-side actions included then I’m pretty sure you can still access those.
The main difference between the two is “where the code runs”. Server-side actions will always run on Bubble’s servers and have no impact on the possibility of breaking anything that might stop your app from being published on either Google Play or Apple stores.
Visual elements however, pretty much always runs code directly inside the browser so that could stop your app from being published. I’m not 100% sure on that but I suspect this is the reason why you can’t see it and the reason why Bubble may have prohibited it.
The work-around is to use the webView component.
Hope that helps, it’s not deceptive!

Thanks. I understand that it could work in the “web view” but this should not be allowed to be classified as “native mobile” (presumably all plugins would fit that criteria).
I understand this may be bubble’s doing, but it needs to be addressed as it is confusing to those of us now trying to create native mobile apps.
