Stickerly Stickers Will Not Load on WhatsApp

I want to use Sticker.ly for WhatsApp, but the stickers simply will not load no matter what I try. I have deleted and reinstalled the application multiple times, waited for days hoping the issue would fix itself, but nothing has changed.

I tried many different sticker packs, yet none of them work. Every time I attempt to add stickers to WhatsApp, the application shows an “invalid” error and the stickers fail to load completely. Because of this ongoing issue, the app has become unusable for me.

I would like this problem to be fixed as soon as possible. I have already tried basic troubleshooting steps on my own, including reinstalling the app several times, but the issue still continues. I hope the technical problem can be resolved quickly so I can properly use Sticker.ly with WhatsApp again.
