The app stopped syncing after the last update and support took a week to reply. We lost orders during the outage and had to switch to a competitor.

About Inline ‑ Critical CSS
With Critical CSS, the visitor gets the base styling as quickly as possible; because it’s right there in a <style> element in the document’s <head>, there’s: no extra request to the server for the stylesheet & no waiting for the requested styles to load in and render. The below-the-fold, or non-critical, styling is then loaded in the background to avoid render-blocking.
Highlights
- Your website will load faster, especially for first time users.
- A faster load time will increase your conversation rate.
- Rank higher in Google with a faster loading site.
