Unfortunately, this is quite a common issue these days across all major Induction cooktop brands. In general, any cookware that contains enough iron atoms to be magnetic will work well with induction—meaning yes to cast iron pans and most stainless steel pots, no to aluminum and ceramic.
The biggest issue today is that as cookware manufacturers fight on price, they are reducing the amount of iron used within the cookware to save cost, greatly effecting their performance with induction cooktops and in some cases, tricking the induction cooktop into thinking the pot isn't compatible. This is all despite brands stating that their cookware is "Induction Compatible". In addition, there are terms like “triply,” “multiclad,” and “hard-anodized” which also can effect cookware's performance with Induction cooktops. Unfortunately the simple test of whether a magnet sticks to your pots or pans won't necessarily indicate whether it will work with your induction cooktop- it needs to be a strong magnetic pull.
Another key thing to remember with Induction Cooktops will have a minimum pot size per zone- this is outlined on the technical data sheet supplied with your cooktop.
To help you make the most of your induction cooktop, we sorted through a number of leading cookware brands to determine which are truly induction compatible— meaning each part of the set can evenly conduct electromagnetic energy and sit flush against a flat cooktop.

If you have purchased "induction compatible" cookware and you find that it's not performing well or even not being detected by your cooktop, you are entitled to return this to the retailer for a full refund.
