    Hi @jlubrecht,

    Thanks for reaching out!

    Can you confirm if your Edge browser if fully up-to-date by clicking Edge > About Microsoft Edge? If there's a new update available, can you update and then try to install the 1Password extension from the following link:

    Let us know how things come along.

    Funny you say that! I had checked the update several times; all reported that Edge was up to date. Re-checked this evening and suddenly Edge updates itself and the plug-in installs right away.

    Working like a champ now. Thanks

  • Hey @jlubrecht,
