I've discovered some more details and patterns to the issue with the new software (4.03.01) causing severe lagging with button response on the home screen. I'm curious if others see the same patterns that I am.
As others reported, after updating to 4.03.01 I started having the LONG lags when trying to do anything on the home screen. I did the "reinitialize premiums" thing, which did fix the issue, but I noticed that I was no longer "signed in" to my LG account. I then discovered that the issue came back a little while after I signed in to the LG account WITH the "Auto Sign In" box checked.
In other words, if I don't sign in, everything remains normal. Likewise, if I sign in without checking "Auto Sign In," I don't get any problems either. Note, however, that when I turn the set off and back on, I am no longer signed in. If I sign in with the "Auto Sign In" box checked, however, I remain signed in, but after some period of time, the severe menu lagging returns. The period of time it takes for the problem to return seems to vary quite a bit. In my tests, it has take anywhere from a few minutes to a few hours. The problem, however, DOES always come back as long as I continue to use the TV with it "Auto Signing In" to my account.
One other thing I've noticed is that when the lagging returns, two of the items on the main menu lower bar show up as little "circles of dots" rather than as their normal icons. These are the "Agent Sudoku" and the "SocialCenter" apps (neither of which I use.) As soon as I reinitialize premiums, the lagging stops, AND the icons for these two apps once again show up normally. As long as I don't sign in to my LG account, the lagging never starts up again.
To all the people that solved the menu lag issues by reinitializing premiums, are you also NOT signed in to an LG account? Is there anybody that IS signed into their LG account WITH the "Auto Sign In" option (i.e. so that it always says "Sign Out" at the top right corner of the home screen) that does NOT get the lag issue?
I can't help wondering if the reason more people aren't reporting this is simply because they aren't signed into an LG account.
Thanks for any feedback on this,
