Hi, OS: MacOS 10.12.6 Browser: all in title, focussing on Safari 10.1.2 Problem: Amazon Video (.co.uk) won't play with ad blocking enabled. In detail: on clicking a thumbnail or Resume link, the Amazon video player loads, plays a trailer, but when it's finished will output a 7031 error code. Works without Adguard ad blocker enabled. Specific conditions: it occurs when clicking on any Amazon Prime Video links, such as: - https://www.amazon.co.uk/gp/video/detail/[video link] - https://www.amazon.co.uk/gp/product/[video link] Workaround: so far, adding (sans quotes) "amazon.co.uk/gp/" to the whitelist works. Less than ideal. Extra information: It's pretty strange because everything was working fine, and then all of a sudden stopped. I haven't updated Adguard, the OS, or the browser lately. I have a hunch that the issue is related to the trailers which Amazon airs before videos. They don't always show them, but often do. When the ad blocker is disabled (or the whitelist edited), then the trailers are often skipped. With it enabled, the trailers always show (and then the problem occurs). Let me know if you need more detail.
