There used to be an option when I pressed on an email in the inbox that would let you choose ‘see all emails from this sender’. Where is this option now?? Entering the sender name in the search doesn’t work reliably AT ALL.
I feel exactly the same as Stacey. This function would be very helpful for tidying up email inboxes. When I copy the sender to the clipboard and paste it back in the search function, K-9 does not find the senders. The search function does not work reliably. It only works with pure e-mail addresses that have no names assigned to them.
