Gia ๐ฌ๐ง Auto request doesn't work on your own accounts, unfortunately.
Sometimes you've paid from sub-account A, but after the payment was made you realise it should've been paid from sub-account B. So you open the transaction from sub-account A, tap "Request > Choose recipient", select sub-account B and tap "Send request".
Now you have to go back to Home, open the payment request and accept it manually. You can't add yourself to the Auto accept feature.
So now it takes several steps, instead of just a few if you could enable Auto accept to yourself.
