Comment 4 for bug 1848621

After i upgraded from 19.04 to 19.10, i faced the same problem, even with syncing turned on for my account in Chromium.

Here is the output when the problem still existed:
$ snap connections chromium | grep password
password-manager-service chromium:password-manager-service - -

As suggested i executed the following and passwords/autofill for logins were working again:
$ snap connect chromium:password-manager-service

Here is the output after the problem was fixed:
$ snap connections chromium | grep password
password-manager-service chromium:password-manager-service :password-manager-service manual

Does this password-manager-service connection persist or do we have to reconnect it everytime?
