I've not had a good experience with Expedite at all. Firstly, despite buying the lifetime all features plan, A LOT of features gave me an 'only paid users get these' alert (I was a paid user). Secondly, I had more failure-to-post alerts than successful ones. And finally, everytime I login, I get an alert to say 'we make all our features free to all users, so we appreciate donations'... after I'd already paid for a lifetime plan..?
It's sadly too late for me to get a refund, but I've moved to Buffer's free plan and it's leagues more robust.
