I am getting this warning message "Your store default currency is currently unsupported." How to resolve this?
If you go to Currency menu in the app, and the below message shows

That is because your store default currency does not include in the list of currencies supported by Transcy.
We're in progress to research, and will add more other currencies in supported list in the near release, so please help me stay tuned.
You can simply go to
Shopify admin > Settings > Store details > scroll down to Store currency

In Store currency section, you can change to the currency as you want if your store hasn't made any sales yet.

Otherwise currency is locked, and can't be changed. You will see a message from Shopify like below. In this situation, you have to contact Shopify support if you still want to change your currency.

Should you need further support, please feel free to contact us via live chat or email us at support@fireapps.io
