It happened on and off the past two weeks or so but was considered not a bug in an earlier report I saw. I also encountered it a few times, but since about 24 hours ago I have had no luck playing anything.
Likely changes or countermeasures on G’s side, or part of the embedded as changes that is being talked about, is my guess.
I tend to stick with Plasma’s own panels but I’ll give this one a spin over the weekend. From the looks of it, it has quite the set of options, which is always fun to tinker with 🙂. Thanks for sharing this.
