Unknown apple ID requests
I have an iPhone X and an iWatch (Series 3). Both purchased new and only ever attached to my appleID. My phone is not jailbroken. I have started getting requests to enter passwords for two other apple ID's I dont recognise. I have no apps recently purchased, none that wont update. I have reset both the phone and the watch with no change. If I dont use the watch, I dont get the sign in requests. I have seen other posts that this seems to be an iwatch OS issue. At present my watch is frustratingly unusable. Does anyone know any other work arounds or fixes.
Apple Watch Series 3, watchOS 6
