Really poor app. Does not work well. Main functions are not available and support is not helping the issue. E-mails look like spam, because it is not possible to change language on basic and important words. I can't recommend this app!
Before you get this app make sure you don't have large store and make sure you are not rotating products in and out.
Otherwise, they will disconnect your store and tell you to sign up for a $99 a month plan.
