Chris,
Thanks for the reply but here's a few follow-up questions regarding the pro version.
If I go to the play store on my PC and click on the pro version it says to install the base version and the purchase provides you with an unlocker key but is this a real key that you would enter into the base install somewhere in the Apps settings somewhere? If yes, where in Settings is this point of entry?
My wife and I have separate Gmail accounts but all of her emails are forwarded to my email address and automatically deleted from the server so at home using Outlook 2016, all of our mail shows up in a common inbox. When I setup our existing email client on her cell phone I did so with my credentials so when she does use the app, which is seldom, she sees my mail, her mail and mail that's common to both of us. If I were to place the order for the Pro version through the Play Store from my phone or tablet while logged with my GMail account will I be able to use the unlocker key I purchased to unlock the app on her phone when her phone is configured with her GMail account or will I have to purchase a separate key for her phone? I can certainly download the base version on her phone using her credentials but I'm fuzzy on whether I would be able to unlock her app with my unlocker key. I have no issues having to purchase a separate key for her phone if necessary but naturally, I don't want to spend extra money when it's not necessary for me to do so.
Along these same lines, If the iMAP credentials used on her phone are my credentials, will the Aquamail still integrate with her list of contacts and her calendar?
Again, if the iMap credentials used on her phone for fetching mail are my credentials, will Aquamail allow me to specify her name and her gmail account as a sender alias for outbound emails? I would prefer that when people receive email from her using the app they see her name and her email address when simply reading her mail and when the recipient were to look at the email header. Can the app be setup to do this?
I'm a bit fuzzy still on the issue of purchasing the Pro version. You indicate that you've been using the Pro version for years but did you only pay for the unlocker key one time or do they make you renew your license with an annual or some periodic upgrade charge of some sort? Most of the apps I've paid for on the Play Store are one time purchases so if you get charged over and over again, how does that work and what is the renewal fee?
