<p>When both clients are new:</p>
<ul>
<li>Alice creates an offer to sell BTC for Amazon.</li>
<li>Bob takes the offer and is instructed to buy the Amazon GC from Alice's <strong>country of residence</strong>.</li>
</ul>
<p>Here's the problem:</p>
<ul>
<li>Alice is running <strong>old</strong> Bisq (1.5.4) and creates an offer to sell BTC for Amazon.  Her account does not include country.</li>
<li>Bob is running new Bisq version that includes this feature.</li>
<li>Bob takes the offer, but gets a failed trade because Alice (old version) did not supply the country in the contract -> <code>An error occurred at task: TakerVerifyAndSignContract Contracts are not matching</code></li>
</ul>
<p>What's the best way to resolve this?</p>
