Thanks for the reply!
I don't fully understand this:
"To start, the Bold checkmark is for transactions that have been cleared or posted in your bank.
While the Thin checkmark is for transactions with corresponding matching transactions in your bank register."
When using Online banking, the thin checkmark shows up when the transaction has posted in the bank or CC company. But you mentioned that is the bold one?
You also mentioned that the thin one was when the transaction matched the bank register. I am a little confused about this too. The checkmarks I am speaking of are in the register.
