@bleachorchid I hope it's OK that I reach out to you, but I saw a review on the Apple iTunes Store with your username, and I wondered if it's the same "BleachOrchid" (a very rare name, so I thought the likelihood was high).
Sucks that the app isn't installing. And even worse, it's not something we can help with on our side. The App Store has been having tons of weird hiccups recently. Yesterday we disappeared from the search results! We're back today, though, so ¯_(ツ)_/¯ How long has it been trying to download?
I hope it self-resolves whatever's going on. If it's still "waiting", you could try tapping on the icon (sometimes that "wakes it up", and it starts downloading again) or, worst case scenario, restarting the phone (but I hate to do that to you!).

Hi Collin, thanks for the prompt customer care. I've tried what you've suggested, and more. Short of wiping my phone, I'm not sure there is anything left to do. It's been "waiting" for about 5 days. If you have an email you'd like me to send some things to, I can send some screen shots and a short clip of what's going on.
