I don't think I even have that option to download the app!
I still have a "gif" tab on my keyboard but when you click it states that I can't use GIFs because its not compatible with newest version of Samsung keyboard.
I think I use GIFs more than actual texting 😓 I think I'm going back to IPhone
Mine did the same thing when I updated. After scratching my head for 2hrs and finally getting fed up with trying to download the app they say is required,which by the way never worked, I opted out by downloading a Google keyboard. After downloading this app from play store I then activated Google keyboard as my primary keyboard and turned off my Samsung keyboard.
Boom. Gifs and stickers again.
I actually like Google keyboard better. More colors, themes and preference options ... Hope this helps
(The app I used is Gboard. "Google keyboard for Samsung")
Just got my s10 last night -after downloading everything from my old phone, I discovered I finally had gifs. Did my first update this morning (didn't used to do updates b/c something always went wrong afterwards but my bf insisted that was why my old phone sucked)...no more gifs. not happy.
Having messaged Samsung this morning I managed to get the native Samsung keyboard working again by doing a soft reset on the phone. On the galaxy s10 plus this is holding the power button and volume down button together until the phone restarts.
Once the phone has restarted, providing you still have Samsung keyboard as your default...open WhatsApp and attempt to use a gif, it will then prompt you to download collector for keyboard.
It now works.
Tx!! Worked perfectly! No need to download Gboard, soft reboot & opening WhatsApp as described did the trick.
Encourage everyone to try this solution as it really did work seamlessly. Frustrating that you have to download app & review it before even testing to see if it works, but my gifs & stickers are all back. Didn't resolve my missing auto- remembered text tho' 😥
As recommended by others, left feedback regarding my frustration & desire for Samsung to fix in next update. Sadly, my auto-text history is likely long gone.
