Hi there, is nothing to do with moisture-is the quality of the plastic and also the rubber of the bottom-after 3 1/2 years is a piece of garbage! It happened to my device! The only available option is to get a 35% discount to buy a new device.!
Same issue … have had my Pro since 2019 and now it is useless. Why buy another, only to be right back here in a few years. Moving on to a better quality product.
Yes I’m having the same issue I tried to clean and it got worse I need the clear plastic to replace and I’ll be OK., but I guess by reading here I’m screwed.
