Hi there!
Sorry for your experience.
The EasyStore is included in Podcast Quickstart pack. But you can only use the version comes with the quickstart pack.
Not to mention, I believe you already know that we have introduced a new Pricing plan for all our products. The current template plan you have excludes the EasyStore subscription. If you want an EasyStore subscription, you have to upgrade to an EasyStore plan. Definitely, any of the EasyStore subscriptions come up with the SP Page Builder Pro, and all the templates and extensions.
I hope this clarifies all the doubts you had in your mind. Feel free to reach out for further queries.
For your another issue, would you please share a screencast illustrating the whole scenario to understand it better? Is there any error on your console?
Best Regards
