nimiqpay://miniapp?url=… opens the target Mini App correctly on a cold start, but if Nimiq Pay is already running in the foreground or background, tapping the same link only brings the app forward. The Mini App is not opened and the URL is discarded — no unknown-link confirmation appears either. Steps 1. Force-close Nimiq Pay. Tap nimiqpay://miniapp?url=https%3A%2F%2Fexample.com%2Fr%2Fabc. -> Unknown-link confirmation appears, the Mini App opens at /r/abc. Correct. 2. Leave Nimiq Pay running. Tap the same link again. -> The app comes to the foreground on whatever screen it was on. No confirmation, no Mini App, the URL is lost. Why it matters It breaks any Mini App that shares links to specific content - a payment request, an invoice, an invite. The person who taps it lands somewhere unrelated with no idea why, and the sender has no way to tell them "force-close the app first". The failure is silent, which is them worst part: nothing indicates the link was received and dropped. It also cannot be worked around from the Mini App side, since the running instance never receives the new URL. Environment Nimiq Pay 2.19.1 on Android 16. Both networks; not network-specific. Expected A deeplink received while the app is running should be handled like a cold start - open the target Mini App at the given URL, with the same confirmation.
