Thank you for your response. However, it did not answer the question I had. According to the specs for the Apple Watch 6, the TOTAL capacity is 32GB, but that doesn't mean I can add 32GB of MUSIC to it.
I own an Apple Watch Series 2, which has a total capacity of 8GB but is limited to 2GB of music, despite there being several gigabytes free. In other words, there's a limitation imposed by the watchOS software unrelated to the actual physical capacity of the device.
What I want to know is if there is a corresponding limit to the amout of music that can be put on the current Apple Watch models (i.e., Series 6, 5, 3, and SE). If so, where can I find that information, because the specifications do NOT provide this information.
