Technical question about DU.

[Weekend Warrior]

About fifty percent of the time DU pages don't seem to fully load for me. The whole pages comes up, I can click any active link on the pages, but my "loading" bar never finishes. The other half of the time the bar goes away in very short order. I'm on an iPhone 7. I don't go to many places where I'm logged in so maybe that has something to do with it. All other functions to my phone seem to be working well. All other sites load quickly. DU does load quickly for me even when it appears to still be loading.

Thanks for and help or education you can give me.
