Odd... I have three Gmail accounts added in the stock Mail App and those are all working just fine. My Yahoo & old
@msn accounts usually have a delay, but it's always like that and always rectifies itself quickly. My issues are with my main iCloud account. Usually I can delete or move an email and those changes are reflected almost immediately on the web and on my MBP, but at times on my iDevices it just says "Updating" at the bottom for maybe 5 minutes ... orrrr maybe 6-7 hours while I'm asleep? Not sure. I've woken up to an 11 on the Badge count but no emails. Just "Updating". Then I check on my MacBook Pro and there's 6 new emails? All of my other mail accounts are fine on my iDevices, and there's no issues with my iCloud Account in WebMail or in Catalina, only iOS & iPadOS, and only for the iCloud mail account. This causes issues with the All Inboxes folder, too, it seems. I'm used to troubleshooting tech issues for work, but in this case there's really no options in iOS or iPadOS for Mail other than to turn it off and on. Which seemed to help! But only for maybe 36 or so hours?
I'm also now having issues with my S4 Apple Watch not working for System Password prompts & unlocking. I can erase & restore the watch and then everything seems to work, again, for like 36 or so hours. Erase & Restore, rinse & repeat. So, the devices do physically work for all of this stuff! Buuuuut only for a bit. Which, to me, means software. And software where the only option is On or Off? I just restored my iPhone 11 Pro Max on Friday, along with my Apple Watch, and everything seemed to work perfectly! ... for about 36 or so hours. Some time on Sunday my Watch stopped prompting me to unlock my Laptop from sleep, and then I noticed it wasn't prompting me for System Password prompts, even though my MBP was showing that it WAS prompting me to confirm on my watch. Sooo, all of the same problems still exist, plus more it seems. I'm finding that my Apple Music library isn't syncing across correctly to my iDevices, either! Again, my MBP is showing correct and the Web is showing correct (Check link below). My iDevices either don't update or at least my iPad seems to update after maybe 15-60+ Minutes? Maybe a couple hours? What a massive dumpster fire the entire iOS13 train wreck has been for me, boy howdy. I'm sure the actual hardware will scream whenever they can get some competent people working again. I normally don't resort to name calling, but when there's this many issues for such a random amount of people (Not a lot! We get it!), all for major functions of some of their most used core apps? It makes me laugh when I read wannabe twitter pundits calling iOS 14 a snooze fest due to it being a spit & polish release. Hooray! I hope? Maybe?? Yay!?
Plus your entire music library on all your devices.
