It's SwiftKey. It did this on my Note 8. They updated the app and it's been like this for a while when texting from the Samsung messaging app
For some reason since I changed my keyboard to Swiftkey...my GIFs are posting as links rather than the animation GIFs... That’s no fun lol,.. Anyone else? Thanks.
I haven’t used Swiftkey in quite a while. For now I switch between the stock keyboard and Gboard. If you haven’t tried Gboard yet, you may want to give it a try.
