The iMX8 CPU was just the most prominent and obviously most important chip we need. The really daunting thing with hardware is, if you miss just one piece the whole production is jammed. So quite naturally the iMX8 was a super scary part, one that we can not replace with another CPU.
Over the course of the last months we have put a lot of effort and also a lot more money behind sourcing parts. We used chip brokers and other sources to cobble together what we could, sometimes paying multiples of the regular distribution price. But also distribution prices have gone up significantly.
With these efforts we have been and will be able to make more phones. We have been pretty consistently shipping phones every week for the past almost half year.
But yes, far less than we would need to and what we would want to 
Maybe as a silver lining, we are right now preparing a next batch for July, if everything works out as we can currently foresee it and what has been confirmed to us by our suppliers.
But please do not cast this in stone! Right now the market is super fragile and unstable. Even comparably small things like a thunderstorm somewhere, a stuck ship in some canal, another COVID lockdown etc. can have long lasting and disastrous ripple effects on the industry since stock / inventory is super low everywhere, there are currently zero reserves.
So the only thing we can ask you for is to stay patient. We are fighting hard every day to get the parts in order to get you the phone (and the other products).
