SUMMARY
I am trying to add my college's Office365 Exchange email account by following
the instructions found here:
https://userbase.kde.org/Kmail/Configuring_Kmail/Accounts/Office_365. I am
unable to add the account due to Duo Mobile authentication, claiming that the
Android version that I am running is too out of date and that I must update it.
I can use Duo authentication just fine on this device on other browsers, making
me think this is an issue with whatever KMail is using to render the web
sign-in system.

STEPS TO REPRODUCE
1. Go to add a "Custom Account"
2. Select "EWS"
3. Put in email address to add and select "OAuth2 (Office 365)
4. Add in EWS url "https://outlook.office365.com/ews/exchange.asmx"
5. Sign in

OBSERVED RESULT
Cannot authenticate with DUO Mobile due to "outdated Android version"

EXPECTED RESULT
Be able to authenticate

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Fedora Linux Asahi Remix 38
(available in About System)
KDE Plasma Version: 5.27.8
KDE Frameworks Version: 5.109.0
Qt Version: 5.15.0

ADDITIONAL INFORMATION
I can add this email to other clients such as Thunderbird without issue.
