Sony WF-1000XM4 right bud draining too fast.

[djeire84]

Hi all. My right earbud is not charging fully and the battery is draining 50% faster than the left one. It's only been happening since the last update (2.0) it's completely broken my headphones. I'm out of warranty and I look after all my expensive electricals. This needs either an update or a way to install/rollback to the previous firmware. I'm not happy at all.
