Recently installed Windows 10 on a new drive to start with a clean OS.
Every time I want to use the Desktop Client or Firefox plugin it says Invalid Master Password. If I log out and go to settings and enter the Server URL for Custom Environment I can log in once and as soon as it gets locked I get invalid password again.
If I then log out and check the settings the Custom Environment URLs are all cleared and I have to enter them again.
On my phone and “Old Windows 10” I dont have to use Custom Environment URLs and login always works.
