I have some troubles with my cover images (of dev-log posts) being not shown on certain platforms such as Discord, WhatsApp... I checked 'Metadata > Promo Images' but that's not what I need since I want to create different cover images for every single of my posts.
Cover images work pretty fine with Twitter so far (adding a cover image for posts after 'publishing' it still does not make cover image to be seen on Twitter, I added the image to 'Social media image' and then removed it, in order to make it work and It seems like my problem is fixed for now).
Edit: Bug in the second paragraph surely exists, but when I added cover image 'before' publishing my second dev-log post, It worked great and can be seen on Twitter without a problem now.
Is there anything I do wrong? I want my cover images to be able to be seen on other platforms too, not just Twitter. Here are some screenshots to explain it better:
