The MyCostPro servers experienced some downtime today throughout the day.
The issue should be fully resolved as of around 17:05 today.
If you attempted to download sales today and it failed, it was due to this issue. Please check point 1 & 2 below.
1. If you saved your file after attempting, please reset your download duration days in the account info tab to go far enough back to capture your last sale, and re query your sold items.
2. If you did not save your file after attempting earlier today, you should be able to resume use as normal now upon reopening the sheet.
Please do not hesitate to contact me if you have any trouble from todays issue (which should be fully resolved now).
Thank you,
Scott
