is this normal

hi guys

my IG account on jarvee follow around 900 accounts a day

the problem is when i check my activity (time spent on Instagram) even after following 900 account
the Instagram show that i spent 0 min on app

who come Instagram wont know that this account is bot since i follow that much of accounts while spent 0 min in app ?

?

I think that's the time you(with your device) have spent on the app.
