When a product is a perpetual beta, you sort of have to expect there will be bugs. And, as time has gone on, its counted on with Windows 10 updates and upgrades.
One lingering bug with Windows 10 1809 (there are others), is that mapped drives disconnect on boot.
Microsoft now has a support article with workarounds that essentially involves running scripts at startup, creating a startup item, or setting GPO. But, each of these is still required to be run at every login.
For most, this is not a big issue. For PCs managed in a corporate environment, mapped drives are controlled centrally.
