Youtube Video flagged after using Pond5 content..

I was reassured both by Pond5 support and these forums that any and all content on this website is considered OK, legal and everything to use on monetized content on youtube, so I am curious, why has my video been listed as "Monitoring for possible review" for nearly a week after submitting the required information about my purchase (i.e. purchase #, with links to both the Pond5 royalty-free agreement and links to the specific songs)..

Can anyone shed some light on this?

PS: It took them less than a day to flag my video, but nearly a week to respond to the claims.

Google (Youtube) is very slow. It sometimes feels like that commercial where a bunch of monkeys are running the show. I have had similar experiences (particularly with RF music) where I had to get the vendor involved. A real pain in the butt for sure. Their matching algorithm particularly in the case of music is really not that great. There are too many songs/music pieces that have similar riffs within them that could match. Of course Google/Youtube just automatically flags anything of that sort. A friend of mine even had his own original composition flagged. Youtube is getting to be a real pain!
