Yes, the pinging sound that jars make as ambient air pressure goes up and down is normal. The button in the middle of the jar lid will never be expanded up from increased air pressure, because jars were not designed to hold pressure in. Automatically, the air would be released. This is all in how they were engineered to make home canning of foods possible. If air were to even build up, the jar would just lose its seal until a vacuum was formed again, or until someone checked by taking the ring off.
So for my jars where the button is not yet deflated due to air pressure/temperature whatever, no action is needed and I just wait it out until the vacuum forms naturally again?
