So in the space of a few weeks Atlassian has told all Forge developers to use forge tunnel --ngrok-config <file> and have now killed that flag and are asking developers to use forge settings set ngrok-config-path <file>
Additionally the latest change results in an error when running forge tunnel as stated here: Cannot start a forge tunnel using ngrok
Absurd amount of collective developer time wasted on these internal decisions. Why not replace ngrok altogether?
