Why am I not able to post...

[OldTinHat]

...on posts I've already commented on??

I get this message. All today and yesterday.

Via the app. Samsung Android.

I've been getting the same message @OldTinHat but I've still been able to post

Hi there OldTinHat. Just so we're clear, have you posted on that thread before under the same name, or a different one? It looks from that screen grab like you've posted under another name perhaps, so that's why you can't post under OldTinHat. But if we've misunderstood, do let us know and we'll have another look.
