iPhone Xbox App not letting me save screenshots

So I have these screenshots I took while playing Sea of Thieves and they're really cool and I want to save them to my phone, but when I open the xbox app and click the share button on the screenshots while in my feed, an error message says

Something went wrong

Sorry, we can't share this right now. Try again in a while.

I waited for a couple hours and still no luck. Can anyone help me on an alternate way to save screenshots from xbox live to your iPhone or Mac?

Thanks

:)
