Hello Andrew,

Yes, you can change it by doing change in paypal app xml file. Refer below mentioned solution for this.
1. Go to root/plugins/payplans/paypal/paypalapp/paypal/paypal.xml, find below mentioned code

	<field	name="merchant_email" 	

				default="" 		

				type="email" 	

				size="50" 

				label="COM_PAYPLANS_APP_PAYPAL_MERCHANT_EMAIL"  

				description="COM_PAYPLANS_APP_PAYPAL_EMAIL_MERCHANT_DESC" 

				/>

<field  name="sandbox_merchant_email" 

        		type="email" 

        		size="50" 

        		default="" 

        		label="COM_PAYPLANS_APP_PAYPAL_SANDBOX_MERCHANT_EMAIL" 

        		description="COM_PAYPLANS_APP_PAYPAL_SANDBOX_MERCHANT_EMAIL_DESC"

        		/>

Change type="email" with type="text" .

Please do the changes and let me know if still issue persist.

That worked - will that be changed in future updates as it worked fine in the PayPal Pro plugin...or will I need to edit again when updated?
Thanks,
Andrew
