I am thinking of upgrading from my loved  RM6 to RM7 (just to be up to date) but have a couple questions after reading all I could find.  When I install RM7, does it use the same file format as RM6  like .rmgb etc.. (When I went from RM4 to RM6 everything changed).  Does RM7 overwrite RM6 or can I run them both?  As RM7 has already been in use for some years, should I maybe wait until Rm8 comes out?  I hate that learning curve so with my luck I will buy RM7 and RM8 will come out the following week..  If there is a video on how to upgrade/install RM7 can anyone provide a link so I can maybe check it out.  Thank you. 

I have been using dropbox with the Roots Magic App on mhy iphone 7.  Lately I am getting a message on the top of the screen when I try to save to dropbox that says "the request to link is unvalid."  I contacted dropbox and they said  "Based on the description you provided, it looks like the third party app you're using is no longer working because it is still using the older version of the Dropbox API, which was recently retired. The developer of the third party app will need to update it for it to continue working.

Please reach out to the support organization for that app for an updated version. If the developers of this app are having any trouble with the Dropbox API itself, they can reach out to Dropbox developer support directly with the relevant technical details for help"

On the dropbox app, it does not ask me to authorize Roots Magic.

How do I contact Roots Magic help and get assistance on this issue?

Thank you..Old Bob
