You beat us to it! This is all fixed in 3.1.0. We tried to make share.supernotes.app as backwards compatible as possible but since it’s a pre-release some things like the open button don’t work as well as intended. In the meantime if you just enter the share code manually in the join code box separated with spaces it will work
Not at all! Always happy to hear from you, we should of made this more clear in the pre-release announcement of share pages. Excited to share with you 3.1 next week!
