Hey,
I've been having a problem since this month where the preview image isn't displayed. I usually change the image every month, and then it appears on Telegram, for example, when you share a link.
Unfortunately, the one from last month is still displayed, even though I've been using a new image for a few days.
I don't need the preview image specifically for Facebook/Meta or Twitter, but rather as a general preview image, especially for Telegram.
