Apple Watch Series 3 battery replacement unavailable despite being quoted an making appointment

Last week I visited the Apple Retail store location to have my Apple Watch Series 3 with watchOS 8.8.2 serviced with an installation of a brand new battery via an appointment. It was discovered that the manufacture of the battery was no longer producing new batteries despite Apple still actively allowing quotes and wasn't made aware of this until I arrived for my appointment. Do you guys think this should be a further incentive to update the Apple Store webpage for when a device can no longer be serviced sooner than later? Thank you for reading this!

P.S. Thank you again for the discount!
