IHG.com for me shows "Spire Royal Ambassador", while the iPhone App shows "Royal Ambassador... yet the Android App shows "Spire Ambassador".
So 4 Jan was the date last year? I was on a completely different AMB renewal schedule (non-calendar year) so this is entirely new for me. My last renewal notice was mid-Feb, 2017.
Thankfully the IC I'm at this week has honored the RA benefits (I haven't even asked about it).
