After realizing that the watchOS 5.1 update bricked my watch on Tuesday, I commenced phone support. After an Advisor spent 20 minutes talking me through the same steps I had already tried, he interrupted the conversation to talk to another affected customer. After resuming the conversation a few minutes later, he passed me to a Senior Advisor, who took my shipping address and said I should receive a return box within 2 to 3 days. The box arrived by Fedex Wednesday morning, and I returned it with the watch that day.
Apple acknowledged receipt of the package on Thursday, and today I received an email stating "Your product arrived at our repair center, but our technicians weren't able to process your repair request. We’re sending the product to you along with a letter that provides more information. If you have questions about the letter, feel free to Contact Apple Support to review your options. Be sure to use the same Repair ID. We apologize for any inconvenience." Included in the email is the Fedex tracking number with delivery expected Monday.
According to the Repair Status Web page, they couldn't duplicate the issue. I wonder what the "letter that provides more information" says. Would the watch have been okay if I had just left it until the battery died?
