## TODO
+- fix crash on pay page
- actually *TEST* subscriptions (and everything else)
-- support in-line QR code with long-polling in payment request!
+- FIXME: do we need the session_id in the QR code? How to pass to JS?
+ => test / check in-line QR code with long-polling in payment request
+ => test session-bound payments!
- LATER: use order expiration from merchant backend (with new v1.1 implementation)
instead of hard-coding 1 day!
