Hmm.. I've been using Jerboa since I signed up about a week ago. It's not perfect, but the only problems I had was last night when my router and access points went offline to update...
Also, I have been using Jerboa for the last 10 hours with minimal bugs...
My accounts are all Gmail or Google Workspace. I have always hated the sorting and display options Gmail allows. I've used desktop Outlook forever and have it tweaked exactly as I want it. I'm paying $99 a year for Office360, might as well get my money's worth.
