Meta description length? | Fresh store builders forum

The noted FSB warns if the meta description has more than 180 characters.

What is the idea behind this, since currently the articles I have read about SEO suggest that Google cuts 154 characters?

If that figure is true, I suggest a change in the parameter in future versions of FSB or even better, a dynamic verification screen as in SEO SEO, that is, when the maximum length is exceeded, the text changes color. This would make it much faster and more accurate when editing or creating SEO entries for products.
