I joined a Teams meeting online recently using Chrome browser and couldn't send out GIF/images in the chat function. Can you please advise how to fix that. Screenshots of the chat function are attached.
Were you joining a meeting organized by an external person (and you're not a guest on their tenant)? If so then that's the way it works. GIFs & images are only available to internal users or guest users in meetings/chats.
There is a UserVoice going to add this feature is you want to vote it up. :)
