Confused about My Notes vs. My Files and missing transcripts - data loss?

Hi everyone,

I'm very confused about how Zoom Hub is supposed to work. 

My goal is simple: I just want to access the full word-for-word transcripts of my meetings.

For recent meetings, My Notes works as expected. As you can see in Screenshot 1, I get both the AI Summary and the full word-for-word transcript.

However, for older meetings, everything looks completely different. As shown in Screenshot 2, all meetings before May are empty and the transcript is unavailable.

In addition, as shown in Screenshot 3, I cannot scroll back any further than March 17. Everything before that seems to have disappeared.

Could someone please explain:

1. What is the difference between My Notes and My Files in Zoom Hub?
2. Are transcripts in My Notes automatically deleted after some time?
3. Why can I no longer access meetings before March 17 (Screenshot 3) and why are some notes empty (Screenshot 2)
4. How do I get access to all my transcripts?

Thanks! The transcripts are very important and I urgently need them for the past 1 year. I have nver downloaded it as I trusted in Zoom.
