I tried doing it on a secondary account, but it still didn't work.
It's not necessary that this is the reason; to be sure of the reason, check the relevant articles on Instagram or contact them to ask. Usually, you can reach any support team through X(Twitter).So, that means my device and I fall into the category of exclusions you mentioned.
I'm using an iPhone and I'm at a loss; I've tried various methods, but while my friends have managed to get it working, I still can't.
After reading through everyone's comments, I feel the same way. This feature is pretty low-key, isn't it?
these rollouts by instagram are really strange sometimes. people will receive updates before others when they actually have the same app version. i would not bother installing the app again since it might not be acttivated for you.
