Importing fixed advanced pricing for group was taking a very long time and failing. When looking at the import history page, when we import a file with 100 or fewer sku's the updated sku's is correct. When we import a file with more than 100 sku's, it shows many more than that being updated. For example, a file with 2000 sku's, for one group, shows that there were 19,000 updates on the import history page and takes around 15 minutes. We imported same file into an older site with magento2 2.3.0 and the history page shows approx. 2000 updates from the same file of 2000. The problem is that our file has around 50,000 sku's so the process never ends. When we load the complete 50,000 file into the old version of magento 2, 2.3.0, the entire file of 50,000 only takes around 15 minutes and shows approximately 50,000 updated. Thank you for any input or thoughts on this.
