I am more and more convinced that they use windows or Linux at work and at home.
If I was employed and saw this rubbish on my device I’d go and fix it immediately, also during my day off!

I am more and more convinced that they use windows or Linux at work and at home.
If I was employed and saw this rubbish on my device I’d go and fix it immediately, also during my day off!

While I would certainly hope they use the devices they’re writing code for; more importantly, it seems they don’t have automated test cases for all sorts of things.

@Banglazed something not working on the wiki. There is no edit option.

Anyone having insanely slow download times? 2-3 hours on all of my devices.

My iPad downloaded in a few minutes. Not done my iPhone yet.

The only betas I install are RC releases.

Anyone finding the random respring bug resolved?

 

[martin2345uk]

The wallpaper dimming bug seems to pretty much be fixed, took long enough.

What was this bug exactly?

 

[Maxell]

iMessage photos not indexing in iMessage photo gallery still not fixed

After installing this RC on iPhone 15pro clock on Home Screen not centered. It was set to the left. Tried to fix it. Ended up doing force reset and that fixed it. Weird…
