I can create a normal subscription. Totally fine. I used to be able to switch subscriptions easily. But since yesterday (at least) when I try to change subscription I am gettinga new error:
"The item `XYZ` cannot be updated to price `ABC` because the configuration `HJL` does not include the price in its `features[subscription_update][products]`."
"The item `XYZ` cannot be updated to price `ABC` because the configuration `HJL` does not include the price in its `features[subscription_update][products]`."
