How do I fix my AirPods Pro 2 charging issue?

Since buying these as supplemental hearing device in March, and wearing maybe once every other day, have had now 4 times when I put them back in FULLY CHARGED case that only one side charged. Took to Apple store, and they thought it was one of the pods, so have me a new pair. Soon all repeated for one side. Next time took in the guy said “just need to clean charging case”. Did this, and POOF, same issue. Odd that when I found the same right one at 2% vs. 100%, when I put back in case to charge up, with ten minutes, hit 17%!!!!

Back to Apple Store, guy ran all sorts of diagnostics, and said “no issues detected”. Did a full reset just in case.

Note…have had 2 other AirPods, one for years, and NO cleaning out charging case, NEVER had this happen?

Experiences? Ideas?
