We're receiving reports that some of our users in Nigeria are experiencing difficulties with their payments.
This thread has been open for a while now and we've checked the status on regular basis with the right folks.
As it stands, the payment issues seem to be intermittent and it's difficult to provide a timeline for a complete fix. As such, we'll be marking this as Not Right Now.
We know that this might not be the update you've been hoping for, but rest assured this doesn't mean we'll not continue to work on providing a good experience and improving the payments. It's just that this will take longer and be incremental, so a thread like this will not be a lot of help.
For anyone encountering these issues, our immediate tip would be to try a different payment method. If none of the available methods work for you, then please post in our Subscriptions help board and we'll happily check if there's anything else we can suggest to support you.
