After 'updating 10.0.0 of Nintendo Switch two new updates have been published, 10.0.1 and the last one, a few hours ago, 10.0.2. From what can be learned on website, the latter solves the drift problem for Pro Controllers, since apparently it would be due to a software problem and not a hardware one.
Nintendo in the official changelog, as usual for these minor updates, underlines only "general improvements to system stability ", but apparently there is something more. Unlike Joy-Con drift, whose definitive solution is only assistance, for Pro Controllers who have drift problems or in general no response from the commands it was all software.
With update 10.0.2 this seems to have resolved, at least according to the testimonials on the web. You also had problems with the Pro Controller Nintendo Switch?
