Animated Stickers not playing on mobile devices
I created the sticker on a windows PC client The stickers works great on PC However it becomes a static picture when viewed on a mobile device (not just me but also my friends) Here’s the sticker link https://signal.art/addstickers/#pack_id=3806e00599303bcbe1b21e3daab6a574&pack_key=96ed9d3b7d0b99d61e01b6cb775badf3615ff305915c94106374c7c1fcf8f015

I had the exact same issue. I found at least 2 previous issues (#4782 #4611 ) that discuss the same problem, but it still hasn't been resolved. Looks like it is a png rendering bug that only affects iOS.
Is this still relevant? If so, what is blocking it? Is there anything you can do to help move it forward?

Same here, seems to be a specific IOS problem, as Signal on desktop renders and animates them correctly. Sticker link: https://signalstickers.com/pack/25c17c28406a7f176a86c6564893f4b7
I'm still seeing this issue as well.
Any chance it could be a problem with the YYImage library that you're using? I checked it out on GitHub and it no longer seems to be a maintained project.
Was able to find this alternative that seems to be actively supported: https://github.com/onevcat/APNGKit
This issue still exists. The animated stickers in .png can render on Android and Windows client but not for iOS.
Here is an example pack

I ran into this issue as well. I recently made a sticker pack with apngs, however only a few animate on ios, while they all animate on the desktop client. I assume it's the same root case, but unfortunately I'm not sure how to obtain the link to the pack again to post it here...
Not sure if my solution would work for you guys. I used an online tool to create an APNG file for my sticker. So it came with meta data I suppose.
Then I used an optimisation tool from the same website https://ezgif.com/optipng. Removed the metadata and re-uploaded my stickers. It actually worked.

Can confirm this works. I used exifcleaner to remove the metadata if anyone is curious.
If you have ensured your images meet all the requirements for a Sticker and they still do not animate, please write in to [email protected] with your debugs logs so we can look into it further.

Hi at all!
I'm almost sure it has not just something to do with stickers, but with playing GIFs in Signal iOS in general. I just sent my partner (iOS, Version 6.38.0.13) a GIF (from Desktop). My Android phone is rendering it normally, but she can't see it at all.
I've found the following issues: #4641 & #5102 They are closed, but the issue still seems to persist.
There is still a problem with this. My animated stickers work fine in the Android and Desktop clients, but it's static in iOS.
UPDATE: ran them in the exifcleaner and they works now.
i have been using ezgif to convert gifs to animated pngs and crop them
I was having this problem when i converted .gif files to animated png files and then cropped the .png files to make them square. I was able to fix the broken animated stickers in ios by first cropping the .gif and then converting it to an animated png
