Hi there, thanks for testing the beta out!
I think this issue is related to this topic, we'll make sure to fix this soon! I'll update you as soon we've fixed that.
Also I'm not sure if this is related, but my WordPress plugin doesn't sync my account information, it still says that I am using the free version.
That's correct! Currently the WordPress plugin and the standalone are two different 'platforms' and are seperated, this is why you need to add the codesnippet to the header of your site (as the WordPress plugin will not do that).
In the Buttonizer dashboard you can see the different platforms by looking at the icon before the items. For example, when the WordPress plugin is activated and linked, you'll find an 'WordPress' icon before it. In the near future we'll update our plugin so you can connect and activate the standalone, then the'll be synced.
