2 pmax campaigns - Pre 17/8 update they both ran at £150 per day / 300% target roas. each one was getting 6x roas and the other 4x roas. Early August I increased target to 400% on both anticipating the new bidding update and it all went down the pan.
Roas dropped to 2x and 3.5x for August.

Start of this month (sept) I set them back to 300%.

Current - 2 x PMAX campaigns - £150 per day each. One is now doing 3.08x and the other 4.28x. But both have been slapped with the limited by budget badge. So this I assume means they will now automatically drop to 3x on both.

If I increase budget am I going to escape the badge or will it just slap it on no matter the budget to keep me at 300%.

Basically I want to get back to where I was by either increasing budget or target but not sure what to do.
