I think the process with built-in plugins is a little flawed right now. I'm using Convertplus and linking that to MailChimp with Convertplus' own plugin to go with it called 'connects - MailChimp plugin'.
It's really frustrating when there is an update to the MailChimp part of convertplus and I can't use auto-update because I can't license key/purchase code.
In order to update, I have to message brainstorm support and wait for a reply. Then explain the situation. They will then give me a link to the download page that usually isn't up to date. After letting them know they then give me a direct link.
The issue I then have is that this new update is treated as a new plugin and not an update to the original one and I have to then deactivate the old one and delete it then reconfigure the new one.
It really would be great to be able to register convertplus so I can just use auto-update to the plugin.
Is there any way to do this because the current procedure to a plugin I get for free with X isn't working very well.
