No Problemo. Basically, I open the GIPHY app and choose the gif I want to use (that’s a bit obvious, IK, but bear with me). I click on it, the gif enlarges, and then, beneath the display there’s a little row of toolbar like buttons. The top, fat right button should be an ellipses {...}. Click on that, another tab should open below it, and choose the paperclip-like button. That should automatically save the gif link (it should actually say “link copied” on screen). Then go back to Wattpad, open the comments, click on the writing area and select paste. Once you send it out, if you can’t see the actual gif (cause it may not load without a strong data or WiFi connection), then the way to tell it actually sent is that there should be a blank space beneath the link. ;)
Sounds super complicated, but once you get the hang of it, the whole process takes like 5 seconds. Hope this helped
