The Sync is not working well and today is the 15th of May and last order was synced on 7th of May. no way inside the app to redo the sync or delete some old data!
Sorry to hear that, we'll make sure it's clearer how you can contact us if you have trouble -did you get the welcome emails from firstname.lastname@example.org?
It looks as though we have data going up to the 12th but I can't trigger a re-import to check now you've uninstalled the app. If you'd like us to fix it up so you can have a look around, drop me an email and we'll get you up and running ASAP.
