That's not how it works. The Advertising Standards Authority nor the Consumer Rights Act cover a delay to the release of a free firmware upgrade.
Stop spreading misinformation and stop trying to stir.
not saying you're not correct Colonic, but in some EU countries, misleading/false advertisement is illegal (haven't checked for delay clauses,but i'm not aware of any), and Netduma is clearly using DumaOS as a selling point on netduma.com. so maybe they should consider changing that or at least come clean about about this issue at hand.
They have endless time to respond on various social media accounts, but fails to use their own platform. to be honest i'm dissapointed like 90% in this forum. but yet the product i bought is still working just fine without DumaOS, and from the social media answers they give it seems it's a bigger handfull to get it done and released. That makes the opening post less trustworthy.
An i believe until the come clean with an update this madness will continue !
Enjoy the summer in stead Guys/Girls
