My source is this Tumblr post, which caused me to check my settings because I just got the latest major update.
I found these settings enabled in my discord app:
I know ideally one wouldn’t use Discord at all, but so many of the nice little people in my phone are on Discord.
BTW it’s never a good idea to allow apps access to your contacts, other than your actual phone and SMS apps.
Stay safe!
It never gave me a message about experimental testing when I disabled it lol. Discord must be doing some real deep testing right now because so many users are having slightly different experiences.
