I use a tool called Grammarly that checks spelling, writing structure, etc. It is a Chrome extension and works on 99% of any of the platforms that I use that allow for text, email, messaging.
I am having trouble with the tool when I generate emails from within Copper. It behaves weirdly (e.g. when I accept spelling suggestions, it inserts the word in the wrong place and sometimes deletes the sentence the word appeared in.)
Am curious if other users are experiencing the same issue.
