Updated to version 3.2.2-0 (20180704).
Changelog: https://twrp.me/site/update/2018/07/01/twrp-3.2.2-0-released.html
The latest official 3.2.2.0 can't mount data (tapping the data mount checkbox does nothing; stays unchecked). I formatted it, rebooted, confirmed data was mountable, then booted into AOSP 8.1. Once rebooting back into TWRP it can no longer mount data. Am I missing something?
Edit: Log message is:
Could not mount /data and unable to find crypto footer.
Failed to mount '/data' (Invalid argument)
Yes..you need a PC
Stock? OEM can only have a backup when you have one of sony's kernels delivered in .IMG flashed into OEM....so if you're on stock...OEM backup isn't necessary because you can't override stock kernel
Thanks. Yes it is stock. So, I even can't flash oem partition for example with flashboot or something? I thought that from twrp I can do everything what I want.

What are you talking about? OEM partition doesn't "override" the kernel, nor it's related to it. When you're on stock firmware, OEM partition will hold an EXT4 filesystem containing customization and apps from your operator or your country customization in the case of a carrier free device. When you're using custom ROMs, the OEM partition will hold the ODM image that you need to flash during the installation of the ROM, generally through fastboot flash oem <ODM image> or through TWRP itself on newer versions. Regardless of what is being stored there, TWRP should backup this partition just fine (at least it does on my phone)...
