Apple Seeds Fourth Beta of iOS 10.3.2 to Developers [Update: Public Beta Available]

.

But is this the master beta?

Hopefully it fixes authentication to Yahoo email via the iOS email client (similar comment for macOS) as the last public beta broke this. Trying to reauthenticate brings up an equally broken text from Yahoo:

(Apparently photo uploads are broken now too...)

I wished iOS 10.3.2 stayed in beta forever, so we never have a changelog, and macrumors has to painlessly speculate every time over what has changed, copy-pasting the same story over and over... With the added benefit to learn to count up to thousandth in plain text, because obviously numbers suck (1st, 2nd, ...1000th).

Hopefully it fixes crashing if some of my 64 bit apps. They no longer open. It's not up to the developer to patch an app every time the mfg breaks their code API.

If you are on a beta you can expect this kind of behaviour, if you don't like it you better be on the regular Updates, normally if Apps won't work on beta's they will work if it's a normal .x release.
It's not Apple's code, it's the developers code, they will update when Apple release the final version.
