I think I’m experiencing the same issue but I’m not sure. I’m still setting up my site and only have 2 users (an admin and a test subscriber). I liked a handful of posts as the admin, logged out and logged in as the test user. I tried liking some posts as the test user. I tried on posts I previously liked as the admin to see the count go from 1 to 2, I also tried liking posts that were not previously liked to see the count go from 0 to 1. I am able to like posts that were not previously liked but the admin user, but for posts that were previously liked, I received the message “you do not have permission to like”. When I log back in as the admin user, I am unable to like a post that the test user liked. Basically, only one person is able to like a post.
I also had that experience. The plugin seems mostly to work, but I think it’s logging IP addresses and or cookies in addition to usernames and complicating use when testing. Seems to work fine for other users, but I haven’t fiddled much with a desktop/mobile playtest.
