You have to submit a support ticket and some of them are worthless. I had to submit to googleplay a negitive review, for the developer to reach out to me to get a new tech support person and he was able to help me get my issue resolved and haven't had any other problems going on 6 months.

Very easy. The support team responds to emails within a few days.

Very easy I had didn't have yo reach out because they reached out first wuth all directives needed.

Not easy.,...,., at all...,...,..., I shouldn't need 50 characters for a question like this.
