Switching to online billing from Apple App store billing

I signed up and subscribed to Blynk 2.0 a few months ago and would like to switch to online billing NOT through the app store. Since my subscription is currently within the app store Blynk.Cloud doesn’t allow me to switch my billing method. Any way around this? I don’t want to cancel and lose devices only to re-subscribe.

Hello,

Sorry, unsubscribing is only supported on the platform where you subscribed. Changing a subscription is similar.
To subscribe on another platform, you must first unsubscribe where you signed up.
