Bug: Universal Link Connection Fails When Kukai App Is Closed

[softstackio]

Description
When attempting to connect the Kukai app using a Universal Link in the form of https://connect.kukai.app/wc?uri=, the connection fails if the app is closed. An error message is displayed:

"An unknown error occurred with the connection. This operation can't continue. Please check the other application and try again."

If the app is minimized, however, clicking the same link again allows the connection to succeed.

Steps to Reproduce

1. Ensure the Kukai app is closed (not running in the background).
2. Generate a WalletConnect link with the following script:

console.clear();
const walletConnectString = ""; // Add your WalletConnect URI here
const encoded = encodeURIComponent(walletConnectString);
console.log(`https://connect.kukai.app/wc?uri=${encoded}`);

3. Send the generated link to your iPhone via Telegram or another method.
4. Click the link to open the Kukai app and connect.

Expected Behavior:
The Kukai app should successfully connect to the WalletConnect session regardless of whether it was closed or minimized.

Actual Behavior:
If the app is closed, the connection fails, and the following error appears:
"An unknown error occurred with the connection. This operation can't continue. Please check the other application and try again."

If the app is minimized, the connection works as expected when the same link is clicked.

Environment:
Kukai App version: 1.1.1
Device: iPhone 14
iOS Version: iOS 18.11
Link Format: https://connect.kukai.app/wc?uri=

Screenshots

Error message displayed when the app is closed and a Universal Link is clicked.

Possible Fix
Investigate why the app fails to handle the WalletConnect URI when launched from a closed state. This may involve reviewing the app's handling of Universal Links and WalletConnect initialization logic.

Additional Notes
This issue can be replicated by using the above script to generate WalletConnect links and testing them when the app is closed.
For context, the issue does not occur when the app is minimized.

hi @softstackio , thanks for the report. This appears to have already been fixed in the latest development build of the app (v.1.2.0). We are hoping to submit that for review this week. Will let you know when its live to confirm this has been fixed
