iPhone 8 Plus pairing contactless reader problems

[SixCrazyPants]

*Update - Left it plugged in for an hour, then all of a sudden it works now.  

Has anyone had any problems with pairing the contactless reader with an iPhone 8 Plus?  I've tried everything in the troubleshooting sections, and nothing is working.  Its fully charged.  When the app starts scanning for the reader, I hold down the button till the four orange lights flash, release the button, the phone asks if I want to pair with the reader (the number matches the SN on the bottom), I select 'pair', it thinks for a second, and says that it failed while four green lights flash once on the reader.  I don't know what I'm doing wrong.  It paired and worked perfectly with my Galaxy S7.
