This refers to the desktop version.
There was a discussion about pending transactions in 2017 - see Pending bank transactions no longer visible on Cash Accounts tab and the feature was re-established.
I am using version 22.1.4 and the pending columns are shown in the bank tab which is very useful. My wife is using 23.8.1.930 and the pending columns are not there. If I click on the balance it simply displays all of the transactions. I do not see any kind of setting that turns it on or off.
Has this very useful feature been binned again? Or am I missing something?
