1Password autofill/suggestion does not work all the time for Snapchat

Hi nullptr7, thanks for giving that a try. I'm sorry the behavior is still inconsistent for you.

It looks like we fixed an issue filling in this app with version 8.9.12 but at some point between then and now a new issue has emerged. As mentioned in my previous post, I've flagged this for the team here.

With a bit more testing I found the following steps to fill both fields but it definitely isn't ideal behavior. This worked for me with Autofill prompts on the keyboard or below the field.
1. Open Snapchat.
2. Tap the password field to open the keyboard.
3. Long press the password field.
4. Tap Autofill or ⋮ > Autofill in the context menu that appears (where you might normally see copy/paste).
5. Tap the username field then select the Snapchat item 1Password is suggesting. Your password should fill.
6. Long press the username field.
7. Tap the username field then select the Snapchat item 1Password is suggesting. Your username should fill.

While I certainly understand it's not as quick as Autofill, when Autofill isn't available, you can also copy and paste or use split screen mode to drag and drop your credentials.
