Seems odd that Apple would fix something that wasn't broken. Could have sworn there was some apple loyalists who said it was working as intended.
I’m a bit of an Apple fan, though loyalist would be a stretch considering I also use Windows, Linux and Android. But I’ve been quite vocal about the bloody mess of iOS 13, particularly 13.2.
Thankfully, having installed the latest beta, opened up about 14 Safari tabs, switched back and forth through lots of apps, including some demanding ones, the Camera and so on. I’ve not had a single unexpected reload.
It was bad for me before the beta, couldn’t even switch between Amazon and Safari without them both reloading (and those were the only apps open).
It’s early days to be making a definitive judgment, but so far, it’s a vast, vast improvement.
Also got another carrier update with the beta, I’m not going to hold my breath, but here’s hoping improvements have been made there too, that’s the only other serious issue I have been having.
