Are you using the low-temperature sealant? It probably has more antifreeze. Might be better at staying liquid but worse at sealing holes. Did you refresh it for the season?

When you got the fatbike a couple years ago I was happy for you trying something new and fun but your reports often seem like it's causing you more work than it's solving

Tubeless hasn't stopped flats for me but it has definitely moved nearly all of them to the garage overnight and not out on the road/trail. If the bike goes flat in a day or three then it's time for more sauce. The holes also sometimes seem to weep more antifreeze but I haven't really tracked it well enough to say if that correlates to a change in sealant quality.
