I had a Google Account (as a normal user) before I used B4x. Later I used these account to develop apps. As you can imagine this is somehow uncomfortable (one account "for all").
Do you have several accounts? What are your experiences?
Many, many accounts. Personal, Business, Club, Family … lots. For software development business, we have a separate Google account for each client that we do development for. In some instances, we'll transfer that account over to the client themselves at the end of our contract so that it's all setup for them and they can maintain the software (and associated Google account details) themselves.
