I want to like this addon, but as others have said, the addon constantly "disappears" requiring to remove and re-add. As I write this review, I'm going to reinstall the addon for the third time this year (mid-Feb) in the hope it will again sync emails properly to Gainsight.
When it works, it's great. However, it constantly disappears causing you to have to uninstall and reinstall the tool.
Breaks at least once amonth
Definitely a MUST HAVE for any serious CSM.
Does not work frequently. When it does work, there is not an option to autolog the emails. You must click "log to gainsight" for each email. If I am going to have the extension, I am going to want every email logged. Wish that was an option that could be turned on or off.
Unreliable - I haven't been able to get it to appear for days.
It's just gone. No longer appears in Gmail. Tried everything to get it back, but it's not there.
When it works it is okay, but like other reviews it has not shown up in Gmail for awhile, specifically since the most recent Chrome update. Would love to see this get fixed.
Good when it works, but frequently disappears and the only workaround is to uninstall and re-install it for it to show up. Right now is not working at all, we are all hoping for the enhancement to be published in the Chrome Web Store.
keeps disappearing and this time won't come back after reinstalling.
