Iwatch Series 5 bubble?

Seems like I’ve read about bubbles happening on the screen of the apple watches series 5 & 6. Last year Apple replaced my series 5 because there was a bubble in the top part of the screen. Apparently, now for the replacement watch a bubble appeared again in the screen strangely at the same area. Chatted with apple customer care and said they can’t replace it anymore as it passed the warranty. Sounds like this is a manufacturing issue and was saddened to know that they Apple is unwilling to help this time. My series 3 is pretty sturdy until now and that’s like about 5 yrs old. Anyone with same bubble issue in their iwatch?
