I released Feed Hawk 1.7.5. This update contains one change: that it no longer uses associated domains, also known as universal links, as part of the web-based (OAuth) login process for Inoreader and NewsBlur.
I made this change for two reasons. First, doing so allows password autofill to work correctly with 1Password for syncing services where you enter credentials into text fields, as opposed to logging in with an in-app Safari view. Second, using associated domains in Feed Hawk was causing bugs in another app that also has goldenhillsoftware.com as an associated domain. It became clear to me that using associated domains in this manner was no longer prudent.
