Wrap create_mobile_seat calls in try-except to catch specific failures (e.g., Android or iOS creation).
something like this

Suggested change

	create_mobile_seat(ANDROID_SKU_PREFIX, web_seat)
	try:
	create_mobile_seat(ANDROID_SKU_PREFIX, web_seat)
	except Exception as e:
	logger.error("Failed to create Android mobile seat for course [%s]: %s", course.id, str(e))
	return
