After 4 days from membership expiration, the apps can still be launched with no error. I have consulted with a staff of customer service. He told me that they cannot access the information from review team, and I just have to wait for the results. I was told that the already installed apps can still be used in 90 days, provided that the apple distribution certificate is still valid. However, I am not able to create new app id, nor generate new provisioning profiles. The renewal submission is about 4 weeks ago, and I am still waiting for the review result.

Same here. Does anyone finally renewed?
