Just typing this at the pool whilst waiting for my kids to finish their swiming lesson.
Facebook is rollin put massive changes.
Several peole reporting ctrs drastically down!!
I recommend you pause any ads where you see impact.
Users will be playin with the new profile.
Tijn
Ps adtech was awesome. More to follow soon.
Yesterday my CTR was up on my campaign! but overnight i saw it dropped a lot so i slowed it down, it just 1 campaign so its hard to say how sure it is.. whats everyone else experiencing?
i don't notice any change in ctr right now..still stable on all campaigns..but to be save i would pause camapaigns until facebook finished their update.
Im riding out the storm.
Ill let you know what happens to those WHO DO NOT 
I'm also noticing no change in CTRs. Everything seems fine to me, but most of my friends on Facebook are complaining about the constantly changing/updating of features, lol
It looks like some users have the new ticker stream that sometimes overlays the ads.
The profile views like timeline wont be implemented for a while. Its just in beta now for developers (awesome though - played around with it today).
CTR's dipped for a day then went back to normal and CTR on some older campaigns are trending upward now.
No complaints so far, looks promising.
Looks normal, they rolled out some type of diff ad look on some layouts i think
