I read recently that Microsoft Azure AD has been updated to allow B2B collaboration, where a User can be provided with access credentials, irrespective of whether they are a member of the AD domain - or external to it:
https://techcommunity.microsoft.com/t5/Azure-Active-Directory-Identity/Azure-AD-makes-sharing-and-collaboration-seamless-for-any-user/bc-p/326671#M768
In relative terms, does this mean that access to a PowerApp (which, to my knowledge, are all hosted on Azure) may be granted to "external" users? A problem I encountered was, although we have AD federation with some of our partners, they were not able to directly access a PowerApp with their credentials - and we had to supply them with a local AD account.
Any news in this area would be greatly appreciated - thanks!
