Q: Why does application give unsupported width error, and ask to rotate device? 'unsupported width' error that states the minimum supported widgth is 320 pixels, please rotate your device to see the full page. Currently there was a minimum height set in banno, but not any width set.
This support 320 min width, which they will do in the current banno integration. They have a border. So even if the screen is 320 pixels wide it is effectively adding 32 pixels of border to make all the 288 pixels in width.

A: Assuming that you're talking about the behavior in Banno plugin framework sizing (specifically, the image https://i.stack.imgur.com/0fx4X.png), then that behavior is within the plugin's content itself and isn't due to Banno.
The "Unsupported Width" behavior will have to be changed by the plugin's author. As noted in Banno plugin framework sizing, the plugin's content must be responsive to adapt to varying widths per https://jackhenry.dev/open-api-docs/plugins/architecture/userinterface/.
