Why 4:5 rather than square
A 4:5 frame is taller than square, so on a phone it occupies more of the feed as someone scrolls past. That extra height is the reason Meta recommends it for Feed: more of the screen is your ad and less is the post above or below it.
If you already produce square assets, they still run. But when you are making a new feed cut, building to 4:5 from the start avoids the most common problem with repurposed creative, which is key text or product sitting too close to an edge that gets cropped in another placement.
Text that fits the limits
The 27-character headline is short enough that most product names plus a benefit will not fit. Treat it as a label rather than a sentence: the offer, the outcome or the product, not all three.
Primary text is recommended at 50 to 150 characters. Longer text is truncated behind a 'See more', so put the claim in the first line and use the remainder for support.
When the footer disappears
Meta's guide notes that with an Awareness objective, or certain reach, impression or engagement goals, the ad footer (headline, description and call-to-action button) is not displayed on mobile Facebook Feed. If your creative relies on the button to explain the action, put the call to action in the video itself.
