This seems to be a recurring issue with Adobe Stock. I need to download a 1gb file, which would take about 10 seconds on any other stock site. I've been waiting an hour. Getting around 500kb/s tops. This has happened in the past and always been written off. But, as someone who has paid thousands to Adobe, I'd appreaciate a better answer than just "clear your cache." Yes, I've tried different browsers. My speed test was 800/800. It is 1000% Adobe's servers throttling.
