Failed to resolve Plugin.Permissions.Abstractions.Permission

Hi.
I'm trying to deploy a Xamarin Forms project to an iPhone, but I keep on getting the build error "Failed to resolve "Plugin.Permissions.Abstractions.Permission" reference from "Plugin.Permissions.Abstractions, Version=2.2.1.0, Culture=neutral, PublicKeyToken=null" CyclePay.iOS". In response, I installed the latest version of Plugin.Permission (3.0.0.12) via Nuget, but I'm still having the same issue. Is the problem that the reference is coming from Plugin.Permissions version 2.2.1.0? If so, what should I do to resolve the issue? Even if that specific piece isn't the source of the problem, any help would be appreciated. Note that the project successfully deploys to Android, so this seems like an iOS specific problem.
Thanks,
