Once upon a time, Microsoft had a delightful little product called InfoPath that excelled in making lovely portable forms that worked quite nicely in SharePoint and Outlook context.
PowerApps reminds me a lot of the user interface of InfoPath forms design, but hopped up on steroids, with occasional huge deficit. The inability to easily forward a form in email is the biggest product deficiency I have yet encountered.
I was able to cobble together a rough facsimile of the view form designed in PowerApps, using Power Automate "when an item is created -> send an email" and essentially rebuilding the form with dynamic content. The glaring issue with this is that the tools to scarf the form bits in an email body are not near as productive as those I used in PowerApps to generate the mobile/sharepoint form in the first place, plus the work to essentially redesign the already built form with crude tools is rather laborious.
This looks to me like an excellent opportunity to enhance PowerApps/Automate functionality.
It may be that my view on this is colored by not having found the secret yet... but judging by all the vlogs and utube clips out in the either on this subject I think I'm not alone.
