I have just changed the image of my Thumbnail used for links, but when I tried the link to my App, it still has the old picture. Right now, I’ve even removed it all together, but it still display the old thumbnail image.
Can anyone tell me what I’m doing wrong? Or is it just a Bubble bug?
According to the link you provided there is no link/og image set on the page currently…
So if a previous image is still showing up in places where you’ve shared the link, that’s just down to the websites you’ve shared it on caching the old image…
There’s no a lot you can do about that… other than wait for them to update it (it might take a few days)… unless (such as is the case with Facebook), you can manually update the image link…
