shopify product photos don't update on youtube

[youtubeheadache]

After seeing how my products photos show up on the YouTube integration, I updated them on Shopify to provide a bit more information to potential customers. That was a week ago, and the images still haven't updated on YouTube. 

I've cleared cache, looked incognito, disconnected and re-connected my store, but nothing works. Still haven't heard back from YouTube help. Shopify help told me it was youtube's problem. 

Has this happened to anyone else?  I'm this close to deleting the current products and creating new ones. 

Thanks so much for any insight or suggestions!
