Invalid packed transaction

Hey,
invalid packed transaction 3010010 appears when i am trying to put through any type of order through newdex.
i have tried to stake EOS into CPU and NET in bloks.io however the same result occurs.
can anybody help me?
regards

Hey there - is this while using Anchor on iOS or desktop, and which version number?

I’m getting the same error on newdex using Scatter iOS 12.1.1. How can this be rectified?
