It's good to hear of legitimate issues. I'm not familiar with Sheets; I tend to use desktop apps (e.g. Excel) so haven't run into that problem myself. And I've never even heard of Workamajig but I trust you
If I may ask, how long have you been using the Web? We got it at home in 1996 so I went through the IE/Netscape wars and definitely favour using local apps instead of browser-based ones, so it's quite possible that my usage - using "sites" instead of "apps" - is causing me to see fewer issues compared with people who were always in the "Web app world".
