takes time to load or not upload message and images to chat history
when I want to check the chat history and back with the mouse scroll back it takes a few seconds to show the message history and upload the images, even in occasion the images are never shown, instead the broken link icon of image, this issue has been using Teams for several months. I wonder why Teams takes time to load messages and images and Skype if you show them right away. Attached images.
Occasionally the broken images will remain broken for quite a long time. For example, today all images in one of my chats were broken for both myself and the other participant for at least 2 hours.
Interestingly, clicking on the image to see the full size version of it did not work either -- this just showed a "broken image" icon.
I'm connected to ethernet, so presumably bandwidth is not the issue (though there may be other things eating into bandwidth). Each of the images I experienced this with were small screenshot clippings that should only have been about 25 KB, though -- not exactly big images.
Workaround: Editing the comment with the image and then re-saving it seems to be a workaround to show the image again. This only worked for myself, though -- other chat participant continued to see a blacked out box instead of the image.
