Facebook’s ads gets rejected for many reasons, but one of the popular ones are where you use images and text and there is too much text int he image for facebooks liking so they reject it.
How to fix text in facebook image ads
The way to fix this is to have only 20% of the image as text and they are tools provide below to check them.
These tools will tell you if your image has more than 20 percent text ratio in your image ad, and if there is you will need to edit your image/reduce font size etc and recheck it. I do my images in canva.com and its easy to get the font size etc. adjusted to make it okay for the ads and to pas Facebook text limitations

Ads that have more than 20% of text in their image won’t be approved to run on Facebook or Instagram. Too much text can look like spam and make people think that your ad is low quality. Make sure to use the headline and body of your ad to tell people more about why you’re advertising and what you want them to do. Learn more about Facebook’s Advertising Guidelines.

(screenshot of Facebook grid tool checker for my image), i had to adjust font and move text a bit below before it passed the test of 20% when it fit in 5 boxes
Six boxes would go above 20%
