I'm a bit lost in the docs for google play subscription price change: https://developer.android.com/google/play/billing/billing_subscriptions#change-price-sub While reading this section one could think that every price change requires a user consent or only increasing the price of an active subscription (like Apple does)
Has anyone made a subscription price reduction and can tell how Google Play behaves?
The play store behaves the same wether you increase or decrease the price of the subscription.
This means, that the play store will send the user an e-mail with the details, the mail contains a button which will direct the user into the store to confirm the price change.
If the user does not react to the e-mail the play store will send a notification via the play store app with the details of the price change. The notifacation will link to the subscription details in the play store where the user can confirm the price changes.
But before the play store will send a notification, you have 7 days to inform your users yourself if you want to. You can do this by either:
priceChangeConfirmationFlow
which displays a dialog within your app. more infoIf the user does not accept the price change before his/her current subscription expires, the subscription will get cancelled.
