Bugs in content types

Hello,

Wonder if anyone can help me with this problem...

The H5P Course Presentations embedded on our Canvas LMS appear stretched when you land on the page the first time. Once you click into the presentation the Presentation reverts to full-size mode (not stretched) so the problem resolves.

The problem is particularly noticeable with pictures, but it also looks strange with text.

Is there a way to embed the Course Presentations in Canvas so that they appear in the correct aspect ratio? 

Thanks,

Our H5P Moodle content isn't show properly on this page in chrome (but works in Firefox):

It seems to be due to this cross site cookies thing with chrome.

Thoughts on how to resolve?

I can not upload images to an interactive video, a multiple choice question or a multiple hot spots problem. I have not tried other programs today.  I have tried using PNG, JPEG and GIF formats and it starts to upload but then I am told that that format is not allowed. This has worked inthe past (at least PNG). Maybe there is a temporary bug today?
