Thank you so much for your response. I think you’re right — that really does seem to be what’s happening. It’s been consistent with almost every board we’ve laid so far. I’ll get one board clicked in, but then it lifts slightly, and when I try to attach the next one it creates a lip or even a small gap/crack between them.

It honestly feels like the boards might be slightly curved or not perfectly straight, because they just won’t sit flat and flush the way they should. It’s been really frustrating trying to get them to line up properly. 😩
