At the moment, we do not support using Flowio app for all development stores, affiliate stores, partner test stores, or users who are still within the trial period of Shopify plans.
We're sorry for this inconvenience. But once you're in the paid Shopify plan officially, you could feel free to install Flowio app and enjoy all of its awesome features.
Hope this will be helpful for you.
Should you need further support, please feel free to contact us via live chat or email us at email@example.com
For partnership or app integration inquiries, we would love to greet you via firstname.lastname@example.org and quick catch up with Ms. Norie via email@example.com
