I am hoping someone can help me, because I am about to pull my hair out. I have followed everything here, https://www.iammancat.dev/2023/03/enable-features-in-older-power-apps/, and I am still getting this,

And now I am getting sign-in errors. None of my apps use Dataverse, they all use SharePoint, so if I am missing some nuisance here, please enlighten me. I have had so many users contact me over the last week, they can get in, but then the App asks them to sign-in over and over again. I spent all of last week trouble shooting this and nothing is working. I thought this was the issue, but even after following I Am Man Cat's instructions (and so many other things) I am still getting the Turn On message. When I look at the ParseJson file, I have no idea which Flag is the right one to turn to True or False. I am so frustrated, and i have spent hours on my Sunday off trying to figure this out. Anyone? Any help would be appreciated.
