I'm going to change from Apple to Android, is this going to be an issue for my subscription?
There are several ways to sign up to Shido.
If your subscription is via Shido.com - changing devices should not affect your account subscription.
If you subscribed via the Apple/Google play stores, the subscription is managed there so if you are planning on changing this you would need to contact Apple or Google to see if a refund could be offered.
