Hi. Have apparently the same issue. Most purchases seem to be there, but specifically one of my favorites "Kaho Imai – 15th Anniversary Special: Ejaculation Denial" does not show up in the DeoVR app on Quest2. It is shown and playable in browser, though (which does not help). I think it was still working a week or two ago.
Let me know if you need more info.
Edit: Apparently there was an update pushed to fix this. However, I'm on the newest app version available to me (15.1.3412), an the issue still exists.
