This topic is very relevant to me. I've been having this issue since the feature came to the public release, I have IOS 26.1 installed, I've tried the lockdown mode trick, which worked once, but then not, and so before I go and agonize as to whether to reset to factory and set up as new iphone, ... which will take me forever to tweek again, is it just reset all settings I should try? And if I back up before resetting, and then restore from backup, won't the problem persist? Please answer this question with a level of tech savvyness that you could use with someone who is not that tech savvy LOL. I'm totally blind, reliant on Voiceover to use my phone, so if I have to set up the phone like new and NOT restore from a backup, I'll be spending days retweeking the settings so it's usable again. When you have accessibility considerations, there' are a lot more tweeks necessary.
Also, someone mentioned in one of the posts about using Outlook being related to this setting. If that's so, and you have access to corporate stuff, does that mean you would literally have to use 2 separate devices to mitigate this effect? So like having one device with only personal email accounts and/or teams, and the other with all the corporately managed stuff? Because that's a great solution if you have a corporate phone, but it's not so great when you don't.
