Several scenarios where "title-invalid-talk-namespace" error is received in Wikipedia app. Error is "Code: 400, URL: ..., title: , detail: title-invalid-talk-namespace".
Navigated to wrong title - redundant "Talk:" prefix, or missing logic for namespace-equivalent talk page conversion.
Scenarios are:
- Navigate to a Wikipedia page through browser (tested with Google Chrome app) -> click on talk page link in browser -> automatically navigated to Wikipedia app with wrong talk page title (redundant "Talk:" prefix)
- Search talk page title through Wikipedia app (e.g. "Talk:Dallas") -> click on the talk page name -> navigated to wrong talk page title (redundant "Talk:" prefix)
- Navigate in Wikipedia app to a page not in main namespace (for example through search box) ->press vertical "..." button -> press "View talk page" -> navigated to wrong talk page title (talk page title not converted to namespace-equivalent talk page, instead "Talk:" prefix is concatenated)
