Hey there @JamieS832
Thank you for coming to the community to ask this great question!
We have seen in the past that some gifs, even when they are under 5MB, will refuse to upload into the library. I can definitely understand the difficulties this may cause, but I'd like to thank you for bringing it to our attention that this bug is affecting you as well. I will be sharing this with our team.
In the meantime I would recommend attempting to add the gif in one of these 2 methods:
You can take the gif to ezgif.com, and select Gif Optimizer. Use the lossy GIF to compress the gif. It does not have to be much, the minimum is 5. This does not always work, but we have had success with some gifs.
Or, you can upload the image to another image host and add it as a URL.
Please let us know if you run into any other difficulties along the way, we're more than happy to help!
