FanDuel bet slip lag?

I've noticed some serious lag with the bet slip lately, especially when trying to lock in live bets or last-minute parlays. It's like the odds are shifting, and my slip just keeps loading or freezing. A couple of times I've missed out on decent odds just because the thing wouldn't update fast enough. Not sure if it's just heavy traffic or if their servers are underpowered or what.

I've seen a few complaints in other forums too but can't tell if it's a wide issue or maybe just my connection acting up. Anyone else dealing with this, or is it running fine for most? Trying to figure out if I should lower my expectations or try troubleshooting on my end.
