## General information
Infinite spinner after a day of Kodi use

### Prerequisites

* [x] Are you running the latest version?

### Description

When I launch Kodi, use Netflix add-on for a while then put my PC to sleep and resume the next day I'm unable to go to any sub-menu apart from My List

### Steps to Reproduce

1. Launch Netflix add-on
2. Navigate through sub-menus
3. Exit Netflix add-on
4. Put PC into sleep mode
5. Wake the PC the next day
6. Repeat pt 1-2

**Expected behaviour:** Netflix add-on should work as usual

**Actual behaviour:** I get infinite spinner when I try to enter any of the sub-menus. Only My List is working. Restarting Kodi is the only way to make the plug-in working again.

## Context (Environment)
Windows 10, Latest nightly of Kodi

### Installation

* [ ] I installed the plugin via zip from the Releases page
* [x] I´m using the Netflix Repo
* [ ] I´m using a different source (Please tell which)

### Operating System

* [ ] Linux (x86/x64)
* [ ] OSX (x86/x64)
* [x] Windows (x86/x64)
* [ ] Linux (ARM)
* [ ] Android

Start by reproducing the Netflix add-on workflow on Windows after putting the PC to sleep and resuming the next day. Trace the add-on state involved in entering sub-menus after resume; done means all sub-menus work normally without restarting Kodi.
