Does anyone have a solution for old users of Google Apps (back when it was called Google Apps For My Domain) that just want it to be like a regular Google account but keep their email address? It's very frustrating that everything Google does may or may not work for those of us that just use Google Apps like a regular google account. I don't use any of the organization features. I don't manage a collection of users. All I wanted was a GMail account with my domain like Google originally offered. I feel like a second class citizen in Google's ecosystem because of my Google Apps account. I'm not even sure what would happen if I tried switch this account to a regular Google account. Google used to (and maybe they still do) allow you to use any email address for your google account but if you wanted to use GMail you needed an @gmail.com address. If I bit the bullet and switched to a @gmail.com account could I keep my data and Play store purchases? I'm guessing the answer to that is "no" so not only would I have to lose my email address, I might have to repurchase quite a bit. Can you import all of your data from one account to another using Takeout? My dream is that Google will offer a "Make this a regular Google account" button. I don't want to change the email address I've used for 15 years just because Google pulled the rug out from under me after getting me to switch to Google apps.
