I changed my profile picture on github quite some time ago, but whenever I share a link to any of my repositories via telegram, it still displays old profile pic. If I share it via skype, correct image is displayed.
I tried to use webpage bot and /updatepreview
command, it says that "Link previews was updated successfully. Check them out!" but the image is still the same (not updated)!
How can I make telegram clean cache for links from my github account?
