Cannot connect to My Cloud

similar issue. using android or iOS can only find files nd folders from my old OS3 device. can access newer files on my PCs, windows 10. tried chat help, no luck. was referred to more advanced tech help. This guy didn’t know anything about issue. at least i think so since his accent was too heavy for me understand. after many hours of frustrating searching on my own have concluded western digital is a really awful company that does not care about their customers. getting ready to buy a new custom pc. was going to buy WD drives. wont make that mistake.
