Redmine

Dear Gentlemen!

I have set up my first Redmine instance on my server, and currently am experimenting with the settings. On the online desktop version everything goes well, but I am a bit frustrated with the mobile platforms. I have tried several of the latters, and RedminePM and MyMine seemed the most promising.

But there are some "issues" with the issues. I have restricted the right to set the attributes for some users, and the workflow goes excellently on the desktops, but both on RedminePM and MyMine these restrictions are almost completely discarded.

First: the users who are supposed to set the issue statuses only to X and Y, are in the mobile app are able to set it to anything.
Second: the users are able to set the priority (contrary to my intentions no to do so).
Third: Time tracking works on neither of the two apps.

And again: all the problems above exist only on mobile; on desktop, everything goes according to my wish.

Any suggestion? Maybe these apps are not fit at all for so a "sophisticated" usage?
(Sorry in case of accidental repeating some earlier similar topic...)

Thank you!
