Stores view explicit words differently.
iTunes and Apple Music want the artist to keep the full explicit words (no covering up by the use of ***). iTunes and Apple want to add the *** themselves for explicit words. The other stores keep the words as they are.
This is what creates a problem: either the titles can be written with all the letters in the explicit words and they will show with *** in iTunes but the word in full in all other stores.
If you don't want your release to show with explicit words, we can keep it as it is and skip delivery to iTunes.
Or, third and last option, you do two uploads: one where you choose only iTunes in the stores and leave the explicit words in full, and one delivery to all the other stores with the release with *** in the explicit words. This way the titles would look the same in all stores.
