Media Sync Idle, Tried Troubleshooting per previous posts

I’ve been missing plenty of media since day 1 when I downloaded v12 from anki ankihub. I’ve already followed the instructions set out in the previous posts (from Sept '23) on how to hopefully get the media sync to stop being ā€œidle,ā€ and it momentarily went from idle to "downloading… But now I’m stuck back at 25 missing files and 19510 unused files after unsubscribing and resubscribing. I had previously reached lower numbers in those categories before attempting the unsubscribe/resubscribe option…
I’ve made sure that I chose ā€œuploadā€ when it gives me the choice between upload and download to anki web.
I’ve tried downloading & importing the media package again.

In addition, I have subscriptions to some of the other media ā€œcategoriesā€ (I guess you could call them?), and I still cannot get those to sync up properly…

Error message (don't change this)

Hello,

What images are you missing?

If you are missing text/extra/pixorize/sketchy images, do the following:

Please try resetting your local changes. To do this:

Go to browse in your Anki → at the top click on ankihub addon tab → press reset all local changes

This will restore everything to what AnkiHub has unless you have specifically protected those fields

If you are missing First Aid/ Additional Resources, you will need to unprotect those fields and then reset local changes. Please see this for more info: Why don't I have all the media in the AnKing Step Deck?

For Physeo media, you will need a Physeo subscription to get the media package for those images
