Sabrina Agreed, the „N/A“ thing should get fixed or just make it impossible to have additional accounts as Easy Bank member. After all, it never really makes sense to spend 20 Euro extra because you could just upgrade to Easy Money or Easy Green which both would be cheaper.
I can tell you that when you are on Easy Money/Easy Green and you create a 26th account there is also no warning. This would be great if it could be added, because not everyone is even reading the pricing list in detail.
