I love the integration. I've had no problems sending to my self-custodial LN and back. I can't send or receive from Strike with error of no route found. The QR scanning appears to be broken on my iOS installation. A black screen pops up and it shows a video recording icon at the top but no image is shown.
It's a known issue with strike that they are looking into. Try restarting your phone.
No luck with restarting iPhone. Hopefully they can resolve it.
