Does anybody use Royal Mail for Seller Fulfilled Prime?

Hi,

Has anyone else seen a sudden spike in Royal Mail issues in the last couple of 2-3 weeks? We have had multiple deliveries going missing and no delivery confirmation. Replacements sent are also coming up with the same generic message on the Royal Mail portal "An update will only be provided when we attempt to deliver your item".

A 24-hour tracked item sent yesterday is showing "We are expecting it".

It's a cause of concern how we have so many 'item not received' requests from multiple days in the last few weeks, more than we have ever done in a whole year.

Has anyone else seen this spike?

anyone else having problems with the buyer/seller messaging platform today?

finding when i send messages from my mail client (Not within Amazon platform) they are not processing replies till hours after. no issues with mail my end as i can send emails anywhere else in under 20-30 seconds to various domains. just the replies i'm sending from outlook to buyers are taking forever to show up in amazon buyer/seller messages. they do eventually show but approx running 4 hours behind for me today.
