I have built several Power Apps that access a SQL Server database located on a VM in Azure using Power Automate flows that call stored procedures via an on premises data gateway. All authentications are my own accounts. My licences include Office 365 E3, Power Apps Plan 1 (Qualified Offer), Microsoft Power Apps Plan 2 Trial, and Microsoft Power Automate Free.
I share these apps with colleagues who have Microsoft 365 Business Basic or Business Standard licences, and they are able to use the apps with no problems. They also usually have "Power Apps Plan 2 Trial" licences, though this doesn't seem to impact on their using the apps.
I noticed a banner on my Power Apps Apps listing website page recently (since disappeared) that said "Your teammates need licenses to continue using your app. Select Get licenses to buy and assign them."
Power Apps licensing has moved on to something completely different from the above. I'm aware of this, but the existing set up works fine so I've not made any changes. I am very confused. Is my set up going to stop working? If so, when? Do I have to spend more than I do now to continue having colleagues with MS 365 licences able to access the apps?
