Could just be me, or maybe an issue specific to my mobile, but I really struggled to get on with plebstr’s web app. Was unable to zap anyone, and the UI was terrible.

Have just discovered that Current has just had confirmation from Apple that Zaps will be allowable and reenabled so I’m giving this a try.
