As discussed in the Slack/Meeting, it would be great for both apps to align the logic with the desktop visual editor -> Insert image and media -> Advanced in Media settings, and that might meet the following requirements:

If size is set as the default (220x124px), we insert it. Instead we should omit it.
If basic is chosen, do not insert basic as a parameter.

Would you be able to refresh the page by swiping it down to see if the issue still exists?

Cannot reproduce it on the latest version. Please reopen the ticket if the issue is present.

The issue is the same as this ticket: T351989 and the one I merged: The RESTBase does not handle BCP47 language code correctly.

"Should not show the additional language variants for non-article pages." should not be the expected behavior: users should able to switch between language variants for existed pages.

The problem might be the full page title passed to the REST API used the HTML display title instead of plain full title text (see the 2nd image attached in the task description).

A side note, the onboarding page should not auto select zh-hans and zh-hant either.

Also (this may be a bit off topic), Pinyin IME is mostly used in Simplified Chinese regions. For Traditional Chinese regions, Zhuyin and Cangjie is more frequently used. If this is distinguishable the functionality could be further improved.

The onboarding screen has been updated. Please go to the GitHub PR above and download the alpha APK to see the changes.
