Great UI but stops working during chats

Much easier to use than the windows app.. but gets locked up and unresponsive after a short time of running. It’s like the earlier poster said.. it “bogs down”. It stops responding during the middle of a conversation and you have to quite the app and reopen it for it to start working again. I hope they address this and update it soon. This is MUCH preferred over the Windows client. Great work on UI, but please fix whatever causes it to fail during normal use.

Not quite like the windows app

Really needs an update and functionality equal to the windows application is needed. Disappointed I had to pay for this and have had zero updates.

Nice start - definitely not as well rounded and feature rich as the Windows app. Some windows won’t close, visitor details normally will not close and have to exit out of the program and reopen.

Very good

Nice app but it seems to bog down after a few days of being open and sometimes I can’t close out of windows.
