Glad lives are back, I was actually inspecting the traffic using my PiHole from when my GF's US tiktok was browsing and when my European account was attempting to connect. Both of them his a CDN within the US but after that it looks like we had traffic going to different versions. Her's was routing to a tiktokv.us while mine was sending traffic to tiktokv. I'm not sure if this has been in place before or if I'm just realizing now but I believe a split-brain scenario is pretty likely.
