If I could step in, I mean our target is to do better than 2020. So I don't think it's a normalized value. I mean, maybe if I could from the CEO perspective, look, there's a software component, there's a hardware component, the software component is going to be very high margin, right? It's 90 plus percent. Then we've got hardware. And we've always said, we said previously that the hardware has been let's say, mid 30s, on average. But that is, we expect that to be going up with volume, as well as designer enhancements, etc. And in long-term, that's still our expectation. I think, yes, we've gone the other way, short-term on the hardware. But that is not a fundamental reset, we're paying a lot more to unpack that a little bit, as you asked, we're paying a lot more for key components. We're also paying higher assembly and transport costs. So we're kind of getting hit from a number of perspectives. We see none of those hits, though to be off the fundamental impairments to go forward indefinitely. We don't have a crystal ball on this supply chain thing. I mean, right now, I think we expected to kind of carryover somewhat into 2022. But we would expect, again, this is a very clear expectation, but we expect some recovery later in 2022. But we certainly hope it's sooner, we don't have a good crystal ball. But what this guidance assumes is that it will be with us to 2021. And again, I want to emphasize the fact that we could probably have higher margins if we were willing to take a lower deal with lower volumes. But, we see a land grab opportunity, we've got real momentum with our solutions. So we are leaning in every opportunity, we have to deploy DAA hardware out there, which means we're scouring the planet right now for the materials we need. And we're paying top dollar in many cases for that. I think that's the right thing to do strategically. I think capturing real estate is absolutely the right thing in terms of our multi-year growth opportunity, our market leadership opportunity. Yes, it's costing us the gross margin short-term. But I think that I think the right way to look at it is, is that we're picking up a significant market share. And that's going to be a durable strategic benefit to the business for many years after this near-term cost headwind is behind us.
