Currently having an issue with our docusign integration within a mobile application. The issue occurs on the mobile build of the app only; in the browser, it works smoothly.

The flow: 

A user clicks a button to sign a form on DocuSign. That button calls a server action to create and display the DocuSign envelope to the user. The envelope receives the URL endpoint from DocuSign, which is set to our dev environment. In the PWA for the mobile app, it redirects to the correct screen in the application. However, in the mobile development build installed on a phone, the user is taken to the default Splash screen. Although the loader fully loads, the flow is stuck there. 

Debugging shows that the actions related to the Splash screen aren't being triggered (breakpoints set do nothing). 

Does anyone know what is going on with this DocuSign redirect issue, and why it's happening only on the mobile device and not the browser?
