All the step-by-step tutorial type bks (think ... for Dummies series) are either published prior to 2017 (usually 2015) OR are listed for the New 2019 release.
I would appreciate suggestions about any suitable bks. And, if I have to get bks that are technically written for a release other than 2017, do you think those for the 2015 or the new 2019 release of the Fire 7 would be more compatible? Thank you for your help!
