A person can be grateful for advice and relieved not to have to follow it.

Advice is a gift, and gifts do not come with obligations. The gratitude is for the attention behind it, for the fact that somebody thought about your situation at all. Turning that into a requirement converts the gift into a debt, and people learn to stop asking. Their life has details yours does not, and their decision can differ without any insult in it.

When your suggestion is not taken, let it go without a follow up. Ask how the thing they chose is working instead. If you are the one receiving advice, you are allowed to say thank you sincerely and then do something else.
