Guildhest Help

Been playing the game for about a week and hit 50. I'm at a point in the main story quest line where I have to do a guildhest on duty finder. I have never ever done one or maybe forgot how to do one. It's currently not showing up on my duty finder so I assume I never unlocked it. I looked up all 3 levequest NPCs and my Limsa Lomnisa (my starting city) quests except for some locked 44s are all complete. I asked FC for some help and I went to the places they told me to go, but still no luck. Most of the solutions I found online are pre-ARR so that NPC is gone. I would appreciate any advice that I have yet to try. Thanks.

For guildhest you need to do all of them in a row to unlock them. So just queue up for the highest one you have available and then go from there. Also look for battlewardens in various camps those are actually the ones that unlock it - iirc there is one in central shroud, one in mor dhona saint coinach's find the rest sadly don't know off the top of my head.

I'm such a noob. I checked my quest journal and there was one that I never finished. Thanks for the help!
