Hmm. I’m trying not to be sceptical. You mention you’ve been using Paperpile since the very early days, yet you joined the Paperpile forums just one hour ago to promote a rival product.
Different Google Accounts (Suite versus Personal) require different logins as Paperpile treats them as independent. Just a clarification that this isn’t the first time I’ve posted on the forum, just the first time from this account. As for your doubts, I personally informed the company of the existence of F1000 quite a long time ago.
I share no affiliation with them. And this is not an advertisement. It is information - hopefully something to shake the Paperpile team into frantic action. Call it tough love.
