AMOUNT_MISMATCH error

Hi, I’m using version 1.0.16 of the plugin and occasionally I’m getting an error: AMOUNT_MISMATCH.

Ive included my debug log below. As you will see, my line items add up to 218.99, but the total amount charged is 219.00.?

I have “Round tax at subtotal level, instead of rounding per line” setting in WooCommerce enabled – I think that may be part of the issue, however I would like to use the PayPal plugin with this setting on.

I can see in version 1.0.16 of the plugin some work was done to fix an error related to ITEM_TOTAL_MISMATCH – so maybe this is a similar error (I also added a reply to the thread where this was highlighted, apologies for the duplication)

Would you be able to have a look at this please?

Many thanks
