> Tim here! Thanks for reaching out to Tablo Support.
> Sorry to hear you’re running into issues on the web app! The problem may be with the fact that you’re seeing this on Firefox and IE. The web app was designed for use with the Google Chrome browser, and we’ve seen buggy behavior from those browsers, as well as Edge. Can you try connecting from Google Chrome and let me know if you experience the same issues?
