Currently I have a SharePint site collection with several subsites for different locations. Each of the subsites have lists with the exact same schema, just the data varies. A user may have access to one or mor of those subsites, I would like to be able to create a single powerapp That would let a user work in any of the subsites he has access to. The first screen would show a list of subsite he has access to and let hin select one. Subsequent scrreens would connect to data in the selected subsite.
Also , this Capability should be exteneded to site collections. Say I use a provisioningin engine to let users provision sites themselves. Each site is identical. I have a powerapp that will work against any site provisioned with that template. Today [I think] I need to create a custom powerapp every time a user provisions a site. We need to have a way to have ONE powerapp that lets the user select the site collection he wants to work with.
