Hi everyone,
Wanted to quickly chime in here. The team does have plans to support React Router v6. We realize support for this may be coming later than expected, but work is already under way.
In terms of rendering issues with Ionic React Router, we also have work underway to simplify and consolidate our routing integrations. Routing is the most complex piece of any framework integration that we build. The main reason is that certain routing components, such as Tabs, work very differently in mobile apps than they do in traditional web apps. This can sometimes result in strange bugs and unexpected behaviors. We hope that by simplifying and consolidating the routing integrations we can provide a consistent routing experience no matter which JS framework you are using.
We appreciate your patience as we work to tighten up these integrations. Thanks!
