I've been told that Adobe Stock is aware that this is an issue and plan to fix it in the near future.
Is there an update on the fix date?
Could you provide a little more detail in your situation? (That will help us to follow up on your scenarios where price filter resets) When you search in Images or with "Standard Content" in All, you are limited to standard content. When asset type drop down changes to Videos/Editorial/Premium, you are not in standard content areas.
It happens when you search within a search.
If I find a photo I like, and search for a similar one or search within the series. The filter re-sets and I'm given options that would cost extra.
When you search in Images as below - you are automatically limited to standard content, and when you search within series as you see on the bottom screen - it searches within the series and currently we don't include premium content in series. I would like to ask a little more detailed description of your experience as I wouldn't be surprised by any user cases where things can go unexpected.
