Unfortunately, this is common and well-documented. AS has stopped making complicated repairs on pre-refurb seats. Back in April, a senior GA said 10% of former VX metal had broken seats that AS is declining to repair. AS has also stopped with the basic leather conditioning that is required to keep the high-quality VX leather clean. I've seen some passengers use the F blanket to cover their very dirty seat.
Here are my previous posts on the topic.
