you for reaching out on the community and telling us about your issue. I do apologize for the issue you're having. I'm wondering here if it might be the mobile sync might be the issue as some users have had similar issues. Lets try seeing if that might be the case. To try go across the top to edit > preferences > mobile & web > Sync off.
Once you've done this try again to see if you're able to get through the one step update. Let us know how it goes!
