Entire friends list has been wiped

First I received a postcard from “Gift”, which was odd because I knew it was from a specific friend and I hadn’t opened it. Then, when I went to call for help in a mushroom battle, the bullhorn was greyed out, I checked my friends list and it’s completely empty. Even the friends I’m doing weekly challenges with have the “Add Friend” option.
However, on my Niantic web account, it has all my friends there.
Have tried logging out and logging in again, list is still empty.
Very frustrating as it’s the last week of the month so I really need to get some mushrooms done, but I can’t send or receive invites.
