Well, I can't speak to your specific situation, of course. It's possible that there is some issue with your hearing aids. But, at least in my situation, that doesn't seem to be the case. My hearing aids work perfectly when they're connected to my iPad, and they were great with my iPhone XS less than two weeks ago. But as soon as I connect them to my iPhone 12 Pro, the trouble starts. Also, I found another post here with other people, even with other brands of hearing aids, having similar issues. I spoke with Apple again a couple of days ago, and, while he didn't have any solid information about a timeline for a fix, he did say that the "higher ups" (Who he put me on hold to speak with...) are aware of it, and that a fix will be coming with a iOS update sometime down the line. Fingers crossed it's sooner than later. I'll definitely be checking daily for any software updates and reading the notes for them to see if they finally figured it out!
