I really like this app. Support is really good too! With this app, I don't need to worry about the rates anymore and if that shipping method is available or not each country. It is always updated especially with shipping suspensions lately due to corona virus. I just hope they also support domestic shipping.

We've been using this app for 6 months, and only ever hit one issue with it, and the support on that was superb. Next day response with a working solution. Couldn't ask for more than that.
