HELP CANT DOWNLOAD APPS

Hey there,

Even if the applications are free, there should be a way to pay in your account.

See this article ☞ If your payment method is declined in the App Store or iTunes Store - Apple Support

~

See ☞ If you can’t download or update apps on your iPhone or iPad - Apple Support

Good luck!

Check that the payment method you can use in your Apple ID first by this link ☞ Payment methods that you can use with your Apple ID - Apple Support

then add it to your account by this link ☞ Change, add, or remove Apple ID payment methods - Apple Support

After you add a payment method to your account, you will be able to download applications without problems.

About your second problems can you explain them well?
