Hey there ! How are you doing?
It seems we also faced issues in making the upload from our side. It looks like the gif is too large, and likely there's a limitation set for it. (Other gifs went in normally)
May I advise you to contact the developer for your application and check with them if there are any limitations?
They should be able to help you in making things work as intended, so you can upload this gif without any issues
If you need help with anything else, do let me know and I'll help you right away!
Cheers!
