How do I disable hint arrows in Splatoon 2?

Solution 1:

The hint arrows don't appear when you're taking too long. They appear when you get an item or unlock something. Take, for example, getting a key. When you get the key, it will automatically start flashing the arrow in the direction of the vault that key goes to. There is no way to disable them. You just need to get to the objective as fast as possible. As for the Grapplinks, there are always arrows flashing like that for level 6. Level 6 is a pretty challenging level, what with the Octozeppelins, and it is sometimes hard to find where you're going. They just put those in to help you with a challenging level.
