Answer 1

I guess you are using ionic native paypal plugin you will find the line

this.payPal.prepareToRender('PayPalEnvironmentSandbox', new PayPalConfiguration({
    // Only needed if you get an "Internal Service Error" after PayPal login!
    //payPalShippingAddressOption: 2 // PayPalShippingAddressOptionPayPal
})).then(() => {
    let payment = new PayPalPayment('3.33', 'USD', 'Description', 'sale');
    this.payPal.renderSinglePaymentUI(payment).then(() => {

The price will be integer like -> 3.33 not string '3.33' in case of android it will work fine but on ios it will crash the app
