Not possible to select the issue type when creating sub-tasks through the screen using the native iOS app

Issue Summary

Using the browser version on iOS devices (iPhone/iPads) it's not possible to select a different issue type on the sub-task creation screen. The dropdown forces to use the same issue type in order to function.

Steps to Reproduce

1. In a Jira project, have more than one sub-task issue type, containing a required field;
2. Create a task;
3. Create a sub-task selecting its issue type;
4. On the sub-task creation screen try to select a different issue type.

Expected Results

It's possible to select the issue type normally.

Actual Results

Not possible to select the issue type in the dropdown.

Workaround

You can select the issue type before opening the create sub-task screen.
