I’ve been doing a mix of both. For example, on pages that I have existing plugins or elements that don’t work in Bubble Mobile I’ve been creating modified copies of them to use in webviews.
For ones where I want to leverage the power of Bubble Mobile (most of them) I’ve just been rebuilding. It gives a good way to learn Bubble Mobile and start reframing my mind from building single page wrapped apps to multi-view apps.
Webviews are a little weird in the sense that you’re displaying a normal bubble page inside bubble mobile. The webview that you’re displaying inside bubble mobile will use all the same workflows and navigation structures as it would when viewing the page in a browser so I would imagine that yes if you’re simply displaying the bubble page in the webview element navigation via url parameters should work the same.
