Delta from seattle

Hello. Hope this is the right place to ask. I have been watching/tracking flight #1562, Delta, from Seattle to Salt Lake City. Delta changed our flight from a non stop to this one. Out of the last 8 days, it has been delayed 6 times. We connect in SLC to go to PVR. There is only one day we would actually miss the connecting flight. Is there any way to find out what the problem is with this flight?( We are leaving a day earlier because of this , as it’s our 50th anniversary trip that we’ve been planning for about 50 years, lol. )
