Have to reinstall app after every call

Cannot edit the numbers

After the new version when we type a contact number then we cannot edit that contact number if we want to change any first number of this telephone then we need to delete whole telephone number as we cannot see any cursor or we cannot touch any number which we need to delete because there is no cursor. Very much disappointed with this new update please try to sort it out ASAP

This is one piece of superb app background everything. Thank you for providing free version I believe if you extend more features in free like call queue, recording you will get more attention such a easy to use interface!
