Nova cover discontinuation

Hi, is anyone else struggling with the unavailability of cover cases for Nova? I was planning on replacing my official magnetic Nova cover as it is quite worn out, but it seems to have been discontinued along with the reader. No other official case seems to be compatible, the unofficial ones are hard to find and tacky. I get it is an older series, but with that high of a pricetag, one would expect that Boox would at least respect their customers enough to not suddenly pull the only cover compatible with an entire series of their devices from the market without proper alternatives available. Does anyone have suggestions for good alternatives?
