I have made a application with sevetal tranactions with steps in each one.
But on Application Health Status only one of them are showing, have verified that all transactions/steps are valid.
Have made other applications with same procedure and they are showing on Application Health Status fine.
Please check that your applications contain at least 1 front-end tier. Otherwise they will not show up. In The business unit screen check the matching data preview section that a Tier is listed and it is a front-end tier
