I haven’t seen it on my dash so I don’t know how late I am to this, but for apple device users, Siri has a function automatically turned on to allow Siri to “learn from this app” with most apps on your phone so it can then learn to make suggestions across other apps.
To turn it off, you unfortunately have to do it manually for each app, but you can find it in your settings > Siri > scroll down to apps > then turn “learn from this app” off.
If this is old news, sorry! I just found out about it this morning and wanted to share for any others unaware.
