Ribbon buttons and its behavior are sometimes Greek for many developers and we might find it had to troubleshoot in case of any issues related to the functionality associated with ribbon buttons. Microsoft has introduced a very handy tool to counter these difficulties as part of an update last year. Unfortunately I came to know about this recently only from one of the blogs “Introducing Command Checker for model-app ribbons“. Seems to be a good read for any technical person working on Power Apps.
