This is the first challenge that I solved in FindIT. That’s because the description of it was very straightforward. They both mentioned "Instagram Feed" and "FindIT Logo". At that time, I quickly jumped into their official Instagram account, @ugm.findit.
I was scrolling through their page and looking for the logo. Once I found it, I looked at the caption. Tadaa! There are some odd strings in there.
