Noticed this as well - Does a "Missing Plugin" still work?
You can actually still access the info from the plugin though, so I recommend recreating the API calls manually using copy and paste from here, but just a heads up that it is using an old version of the Stripe API: https://bubble.io/plugin_editor?id=1479889706470x214621824559611900&tab=tabs-1
Or wait until Zeroqode or the author of the plugin release fixes or a new plugin.
