"Form validation code expired. Please refresh page in order to continue."
We have strange issue. On our site, there is no cache plugin. Turn nonce is off. For some users it works fine but for others not. It says about validation code expired. No matter in what browser it is opened in the same device. On one device it works, on other not. We have tried demo forms here on your web and it works fine in all devices. I am not sure what the cause is. Could you please advise?
