Cannot 'Renew' a subscription after the current one is cancelled

[saraolson]

Steps:

1. Cancel a subscription (ie 1-month sub)
2. Go to the subscription screen and tap the Renew Subscription button
3. Select another subscription, ie 3 month sub
4. It puts you back into the sub screen with nothing changed and no IAPs recorded on our end even though Google Play took the payment (takes about 5 min to process)

Looking at Playstore subscriptions will show the new sub with the 'confirm plan' label.

What should happen: should charge right away and start the subscription, giving out proper benefits. This was found when a user wanted to switch to a 3-month sub to get an hourglass but couldn't.

Was able to test with a gift sub and successfully upgrade to a 3-month sub, puttin my remaining sub balance into additional credit. can't test cancelling a sub right now due to some issues with test sub cancellation happening at midnight on the current day, causing immediate removal of benefits even tho the sub has a short active period after cancellation.

had a report of this not working for someone on 3/24 (22e04ed2-c2c4-4673-83f1-4fe767f78668).

google play showed the 'confirm plan' language and eventually refunded the charge. so this seems to be a 'sometimes' it doesn't work issue?
