I am using typo3 10 and the latest bootsrap package. My problem on an Iphone it won't display my background images, just the background color.

Start by reproducing the carousel background-image problem with TYPO3 10 and the latest Bootstrap Package on an iPhone. Inspect the carousel and its background-image behavior in the package; the issue is done when the background images display correctly instead of only the background color.
