Quick note: saw this thread yesterday and checked my account. My first year of my E+ renewal period ends (or used to end) in April. With the extension, it now ends in October.
Yesterday, all my miles earned in May through September were no longer being counted. At well over the first year renewal E+ renewal requirement, that made me a little nervous.
Glad to say it’s been resolved and the app tells me I need 0 miles to protect my (now extended) E+ status.
Figured yesterday that they’re just working through the kinks before announcing it, and seems like that’s true.
