I suspect it is quite possibly a supply chain issue as Habs alludes to, presumably they are manufactured in China and there seems to be significant delays with stuff coming out of that country at the moment.
Perhaps people are also using their smokers more given many have more time on their hands currently and Bradley could have been caught out by an increased number of spare parts requests particularly if they operate a “just in time” supply chain model rather than keeping high volumes of spares available?
I would add this is purely conjecture, Bradley are not always the best at communication and I would phone / email them for the official version!
