Localstorage isn't working

Hello voltbuilder team. I am using voltbuilder for 1 month. Yesterday I uploaded my web application to voltbuilder which is using localstorage. But in the apk version localstorage isn’t working. Please tell me the solution

First thing is check for messages on the remote console. Here’s some information on how to do that.

But It is not failing at runtime. It doesn’t work when I call the function localStorage.setItem().

I’m sorry - I don’t understand. If it isn’t failing at runtime, when is it failing?
