Ran into minor import bug:
If the same listing title of an item is used but the capitalization are changed, the title will not update.
i.e mens flowered shirt size XXL changed to Mens Flowered Shirt Size XXL
The import will not change the capitalization of the words.
You must change the word to something else and then reimport twice.
Not a big bug, just caused us a few headaches trying to figure out.
I will create a support ticket on your behalf and if the testings procedures carried out from our end will confirm this scenario, an issue will be reported to our development team so that they can fix it.
Kind regards, Natalia
