Cashtab Chrome extension - impossible to "Claim Reward"

Hey guys,

FYI, I've noticed the claiming reward (CACHET) function isn't working anymore through the chrome extension.

There isn't any error message it simply doesn't work.

I've tried both on Chrome and Brave, same result.

Begin by reproducing the Cashtab Chrome extension's Claim Reward flow in Chrome and Brave, recording any console or network errors; the issue names no files or tests. Done means the CACHET reward can be claimed successfully and the behavior is covered by an appropriate regression check.
