I purchased a few apps a few years ago, and my credit card expired a long time ago. So if i close my payment profile on google play will I still be able to install the apps I purchased?
It appears you are confusing payment method with payment profile
- If you close your payment profile then you can't install earlier purchased apps as explained in Google payments center help
When you close this profile, the service(s) below will be canceled:
Google Play Apps
Google Play Movies
