Wavebox picks the wrong Gmail account after signing in

When signing into a Gmail account using Wavebox, normally it shows the inbox for the first account (the primary account for this session) you signed into within the space. If you've already signed into a Gmail account within the space, you may find that after signing in, it shows the wrong account.

If you want to use a different Google account as the primary one for the space, you need to sign out of the other accounts first. Here's how to do this...

First, in Gmail or any Google site, click on your account icon in the top-right of the tab. From here, pick "Sign out of all accounts"

Once signed out, your accounts will still be listed. To remove them click on "Remove an account"

Use the red removal button next to the account and repeat this process until no more accounts are listed
Finally, you'll be asked to sign back in. Use the primary Google account you want to use in that space
