User signed out daily

I’m an application developer working on a hosted web app for LG WebOS. My app allows users to sign in and the signin token is currently stored as a persistent cookie. I’m running into an issue where if a user has quickstart+ disabled and signs into the app, they will come back the next day and find that they’ve been signed out. If they simply turn off their TV for about a minute and come back, they will stay signed in.

I’ve read that I should use LocalStorage instead of persistent cookies because when TV restarts with quickstart+ disabled, it will clear the cookies. But if the issue was the cookies, why would the user stay logged in after turning tv off for one minute and turning it back on?

Do you mean that your cookie remains when QuickStart+ is on, but not when it is off?

Yes it seems that this is what’s happening but I can’t seem to narrow it down exactly. I would just like to confirm whether this is normal behavior.

If you turn off the QuickStart+ and then turn off the TV, AC will be cut off immediately, so the last modifications will not be written and flushed to the eMMC. If you save a cookie 1 minute before turning off the TV, the cookie will remain even if the QuickStart+ is off. However, to optimize TV operation, we recommend that you keep the QuickStart+ turned on. Thank you.
