Not a very helpful screenshot. Either you don't have card drops left or your account is restricted because steam requires it be funded or game bought off steam store.


Idle master reads your badge page, linked here, it looks for 'card drops remaining'

Steam gives the cards(not idle master), Steam only gives half a badge set number of cards.

You need to buy the rest or trade for them:

Free-to-play games do not drop cards unless you spend lots of $€£ on in-game purchases or DLCs

Ok but for example I have badges to collect of a game called terraria and it didnt collect it.
It only says idling
