I use Proton Mail, Pass, Cloud and VPN. My login requriements are slightly different depending on which Proton app I chose to log in first. Is there a recomment sequence for opening your Proton account?

What I find

Method A
1. Select Proton VPN from Taskbar than Quick Connect
2. Select Proton Pass and it opens without entering a passphrase.
3. Select Proton Mail from Proton Pass, site opens, credentials automatically loaded.
4. Select Proton Mail from the list of available Proton apps, mail opens, and Proton clover leaf reveals all Proton apps.

From here if I choose to open Pass, I am asked for credentials, and they are automatically entered after I confirm the email address.
Method B
1. Select Proton Mail from my Taskbar, it opens and the Proton clover leaf displays only the mail apps.
On the left side of the screen, I can select other Proton apps and find the VPN app is active.
2. At this point to get to Proton Pass, I must open a browser and enter my credential username and passphrase.
Method C , My Practice
1. Open Proton VPN from my task bar and Quick Connect.
2. Open a browser and select the Proton icon, it opens Proton Pass where I select my Proton Mail App
3. On the subsequent screen, I selected the Proton Mail app again and now my Proton clover leaf has all the Proton Apps I use.
From here if I select Proton Pass, I am asked for my credentials – I confirm my mail address, and the passphrase is automatically authenticated.
