I think it turns out you were right, and I might return the Oasis. Before even opening the Cigar Oasis packaging, I checked my digital hygros on the apps (some are Boveda Butlers, some are Govee mini’s), three times today, and my levels were absolutely consistent. 65% in the bottom two trays and 66% in the top three. I had a ton of 65% Boveda and placed, I think, around 35 Boveda in there - 6 to 8 on each level. I bought the Oasis because I thought circulation would help maintain equal humidity amongst the different shelves. Turns out, the Boveda is doing its work, even in a 3.2 cubic foot wineador. There are at least 30 cigars on each of the five levels, about 75 on one, which also helps.
Returning the Oasis would allow me to get more T52’s, Padrons, and Aging Rooms. Sounds like a plan...
