Yesterday I flew with 3 batteries with no problem with distance and altitude using OTG cable, charged the batts last night then flew this morning with altitude and distance limitations went into settings no matter what I do it won't let me save the settings it keeps coming back to 50m altitude and 100m distance.  Finally to my frustrations I disconnected the OTG cable and went to wifi connection then only then it let me saved the altitude/distance.  Sparks oh sparks, everyday is a brand new day with this drone.  That's all folks

Can the Mavic RC cable,which is used to connect the Mavic Remote to a mobile device, be used for the Spark to connect a mobile device to the remote?  They both have the same Micro USB on the remote.
