I recently began a newsletter using The Newsletter Plugin, and heard from two subscribers in the last couple of days that when they tried to confirm their subscription from a mobile phone browser (one Edge, the other Chrome, so maybe it’s unique to Chrome-based browsers) they got an error result after entering the correct answer to the math question. When they then tried a second time, each got the error message I set up for people who are already subscribed. When I looked them up in my subscribers list, they were listed as “confirmed,” so the double-opt-in mechanics behind the scenes apparently worked.
I’ve deactivated both Akismet and Captcha, tested from Edge on my own phone, and had no problems, so it looks to me like it’s either the Akismet integration or the Captcha component.
Is this happening to other folks? Is this a known issue? Or is this unique to me in some way? I’d really love to turn Akismet back on, but I don’t want to do so and start blocking mobile users (again).
