Thanks so much for that context, @mhterra !
I was able to find the app’s documentation for you which details how to correctly set up the app along with managing subscriptions. Please do review that along with your existing configuration to learn what the issue is.
Furthermore, if you’re still unsure then I welcome you to connect with the app’s developers directly. I trust they will be able to provide you with personalized support and review the set-up for optimization.
Warm regards,
