There are threads here specific to LTD and unum.
The best advice I got hands down is from Linda Nee. Her blog is a must read for anyone going through a claim. With any insured.
I wouldn't use the word "interesting" to describe dealing with unum. They are evil and Habe goal . To deny claims.
Everything Linda Nee talks about they do. This ain't no joke and when your financial independence is In Their hands you do yourself a terrible disserve by not taking this seriously.
I'm sure ophthalmic surgeon who was denied his claim because they said he could still work after his diagnosis of Parkinson's, did not call dealing with unum "interesting"
