Known workarounds for specific websites
I'm having trouble logging in to Delta.com
You need to open the details for your Delta.com password in Dashlane and then uncheck “Always log me into the website”.
Then, you need to go to this site via your browser and not by clicking on it from Dashlane. This is because the automatic login won’t work for this site.
If you go to the site from your browser (by typing in Delta.com in your browser), Dashlane will fill in the first two fields with your login info. Then the Last Name field will appear. You need to click in the Last Name field to fill this in and log in.
