hi, i have a unique problem regarding localstorage and auth_token. In my next js web app, auth_token is stored in local storage, through CTA user is going to external site inisde the same window, and again comes back to my site, there user syncs insta through 3rd party service, but when in the end user is re-directed to a route of my site, then for some reson auth_token for my site is removed from local storage . How is this possible ?
