The Orders cannot be imported from Channel if there were a lot of Orders updates made at the same time
If you have any tool or script in use which updated the Orders data, most probably, there are a high number of changes made at the same time to the Orders. Previously, M2E Pro used the method when it checked the date of the latest synchronization of Orders data and started the next import from this date. But using this method, the orders import might be stopped that was related to the amount of importing orders.
In this M2E Pro version, this functionality was completely re-worked. New, special programmatic part was implemented into the Extension, which allows to proceed the further Orders importing/updating. This new functionality is solving this issue for Sellers with a high activity, large inventories and high number of Orders.
The delay in the Orders downloading if there were a lot of List/Revise/Relist/Stop actions running
In case you have a lot of Products in your Inventory with the high number of changes in them, the number of required List/Revise/Relist/Stop actions which should be executed is also high. For Sellers with the high-loaded systems as described above, the time-delay in the importing/updating of Orders might arise.
In this M2E Pro version, this functionality was improved. The completely new, special programmatic part was implemented into the Extension, which allows to proceed the Orders updating and minimize the possible delay. So, the issue with the Orders updating/importing delay should not arise.
