Incorrect featured images

Hi. I uploaded a picture to use as a featured image, but when I went to preview the post before publishing, it showed a different featured image, one I used on a different post a while ago. It only seems to have this problem on one of the devices I use (an ipad pro), but not other devices I use, like my phone or computer. Even with account syncing across devices, it won’t show the correct featured image on the ipad, regardless of whether it’s correct on the other devices.

I was able to get the correct featured image to show on my computer, so I published it. If I go to my website on my computer or phone, it’s perfectly fine. But if I go to the website on my ipad, it still shows that same, incorrect featured image. Is there a way to fix this? This has happened on other posts of mine as well.
