DO NOT USE THIS TAG FOR NEW QUESTIONS UNLESS THEY ARE ABOUT CHAT! Use in combination with [chat] for posts about the mobile versions of the chat sites. The mobile views of the main sites have been removed.
Use this tag in combination with chat to ask a question, report a bug, or request a feature about the mobile versions of the chat sites (new or old).
This tag is also used on old questions about the now-removed mobile versions of Stack Exchange sites. These mobile views were first deprecated and then fully removed from the network over the course of 2021 into 2022. The last phase of this removal took place on March 2, 2022. As such, feature requests and bug reports for these views are no longer applicable.
For questions about the site's current design on mobile-sized screens and devices, use responsive-design instead.
For questions about the mobile apps, use the android-app and the ios-app tags instead (note that these platforms are no longer supported, and their components are being decommissioned as needed by Stack Exchange).
