I’m trying to rebuild a coherent context for what the possibilities for mobile support are for a Marketplace app. Let me summarize my findings thus far.
There is no support on mobile for Forge apps.
This Trello card (archived) makes it clear that the mobile support for Forge was deprioritized and is not being worked on: Trello
Connect apps making use of the following modules are supported on mobile by Jira Cloud: Issue glances, Issue contexts, and Right context web panel*
* This comes with the caveat that only Issue glances are going away soon-ish:
Jira issue glance module in Forge or Connect app being deprecated and replaced. This module is being deprecated and replaced by Jira issue context module on Oct 6, 2023. Check out How to future-proof your Issue Glance implementation on how to migrate.
This documentation outlines the recommendations for adding mobile support: https://developer.atlassian.com/cloud/jira/platform/developing-apps-for-jira-cloud-mobile/
Does this track with the real world or have I missed something?
