I noticed that when I create a new deal, the system allows me to chose a company and a then a contact that has nothing to do with that company. is this behaviour by design or is it me who missed a configuration?
if it's by design, why doesn't the system filter contacts based on the company chosen?
it is a very annoying behaviour, especially when you start to have many many contacts.
I noticed the exact same thing the other day. While I can't say if it is by design, it is the expected behaviour and not due to a setting you have missed.
Testing this morning however I was able to confirm that in the Search contacts box, if you type part of the company name HubSpot will bring up contacts with that domain in their email address, so you can quickly filter by people at the same account.
