I had updated my apple tablet to iOS 18.1 have had nothing but trouble with my notifications ever since. Before I installed that my tablet was running great that’s why I bought Apple products. I had called customer service on 12/18 about not getting notification alerts on my email app on either device. A numerical number or a sound alert. And I do count on those alerts so I don’t have to go into my tablet where before if I missed the sound alert a number would be there. I talked to a representative and he took over my tablet and I thought I had the problem fixed…but unfortunately that was not the case. So I called again 12/19 and retold the same story so that representative took over my tablet and undid the other representatives former corrections and told me to update ios18.2 which I reluctantly did after my bad experience with 18.1. He also took over my tablet and reset it with no resemblance to the man that set it up the former day. Still not getting any number or sound alert. I do love my apple products for their reliability but am sure I will be thinking my choice when I do an upgrade. I will say you have the nicest customer service people and are very patient with a non techie like me. On final note this iOS system sure isn’t battery friendly I can’t believe how fast my battery gets depleted.
