I have a few questions:
• Do you have the ad size (height x width) for both Facebook and LinkedIn

Are these animated gif ads that will show 3 slides for each ad?

Hello,
Yes I do confirm each ad will be a 3 slides'slideshow.

Here are the Facebook ad specs for slideshow ads:

Images:
Size – 1,280 x 720 pixels
Ratio – 16:9, 1:1 or 2:3
Format — .MOV or .MP4

Do you need any additional information?

I’m not sure I understand the PDF details. Also the WeTransfer link you provided no longer work.

• For the TrueMedia Agent ad, what’s supposed to be on each slide?
• For the 3D Service ad, what’s supposed to be on each slide?
