@Wosven @R C-R We only want the Affinity files to lock once a user opens it. Remote, On prem, Server, Local, should not matter. These applications should work the same as other applications such as O365 Word, Powerpoint, Excel, Adobe CS Photoshop, etc... (and almost every other app on this planet).
We are a firm with 5 offices and have the infrastructure in place to effectively work together on all aspects of a project whether you are in an office or at home with zero issues accessing files. Overwriting someone else's work is (was) a thing of the past until this issue appeared. Yes, it's user mistake by selecting Replace on the file but there should be no chance for this to happen and lose work.
