I submitted a support ticket and PF was able to resolve. As for Trust_The_Cat's remark, the actual last tiles were no where near the area the LTF was leading me to. And yes, I did try moving to other directions before re-activating it. I also tried in WebGL and on the Samsung, it was just not working as should.
TLDR: If LTF is not working in this event for you, submit a ticket. They will get back to you within 24 hours.
