AI had a fault with my AW 5 not alerting me with the Haptics as it did before I put the latest update on. Apple, when I phoned them ran some Diagnostics on it and said I needed it repaired. I sent the watch in and received an email from them saying that they couldn't process it. In the meantime, I have been wearing my AW4 without a problem and the reason it couldn't be processed is they said nothing was wrong with it. Since wearing my AW4 I have noticed there's not as much storage on it as the AW5 so I'm wondering if they're correct whether its a software issue and the software causing the issue is not on the AW4. so my question is how do I delete the software that not on the AW4 to find out.
