I'm having a strange problem with Facebook Ad designs in the Creative Hub. I reached out to Facebook several times with no luck and figured I'd tap into this community to see if anyone has experience designing these.
I am doing a 1080 x 1080 pixel ad and on mobile all of these ads are considerably blurry. I do not experience this with the Desktop versions, they are completely clear.
I have ensured the dimensions are correct (1080x1080) and have tried 2x and 3x of the dimensions with the same results. I understand Facebook quality is not the best but in this case it's completely unacceptable, all images on mobile that I upload are very blurry. I even experimented with actual photos instead of digital illustrations and I have experienced the same results. It's frustrating because I see crisp ads on Facebook all the time and I feel like I'm missing out on some kind of secret. For the record I am using Adobe Illustrator CC and using Export > Export for Screens for this example and when using photography I am using Photoshop CC Save For Web & Devices - they get the same results.
Any feedback and knowledge would be greatly appreciated.
