IMO push notifications in the OS from the app should be reserved for messages about transactions, money coming in, dividends etc, not for marketing or promotions. I’m considering turning off push notifications on the freetrade app as a result of receiving a few repeats of this message about sharing via a freepass. Don’t make me do it!
It’s fine to use other channels for marketing stuff (email or possibly in app notifications), but notifications on my phone need to be reserved for actions to do with investment, not promotional messages, or I’ll just turn them off (as most users would I imagine). If we let all the apps on our phone send such messages we’d be inundated with marketing all the time so any app that does this to me normally gets notifications killed immediately (making an exception for freetrade for now).
