When I am in nextcloud talk, pictures in chats are not previewed

when I open my chats, I can’t see what the image is before oppening it and I must open an image to see the content. however this wasn’t the same in the past.
is there anyone who can help me?

I have used ios, windows and android and the problem is the same everywhere

I’ve the same issue. Actually I didn’t see anything interesting in the logs
