Beta app expired, no testflight update to redeem: can I save my data by downloading the release version of the app?

I have been a beta user of an app via TestFlight for a years--I complained about some bugs and helped to get them fixed and it was getting so smooth and easy I forgot to keep track of expiration dates. Yesterday morning everything was fine, yesterday evening I clicked on my app, and got a message, [beta app] expired. Went to TestFlight, got 'ready to test' default message. Checked my e-mail and there was not the usual 'new version available to test' message.

I've sent a message to app support and am waiting to hear back from them. They're usually pretty prompt, but in the meantime, I thought some of you here might know the likely answer to this question: if I just download the current release version, will it recognize my beta app data file and open it so that I get seamless access to my data with all of my preferences and customizations intact?

I did not get a notification that I was being dropped as a tester, so I did not have a chance to export my data and honestly am not sure how much of my preferences/customizations are available in that built-in export option. None of the data or preferences are life-changing, so losing it all is not a crisis. But it will take several hours to recreate the basics and months of occasional annoyance in regular use to get all of the little refinements back to how I like them.
