How Do I Recover My Smule Account After a Number Change?

I have been using Smule on an Android phone for a long time. About one year ago, I had to change my phone number, and since then I have been unable to log into my Smule account. Because of the phone number change, I can no longer access my original account.

So far, I have not contacted Smule support through any channel. My old account contains recordings and connections that I created with significant effort, and I would like to regain access to them.

I request that the phone number associated with my Smule account be updated and that my access to my existing account be restored.
