I am a Apple computer fan. I have iPhone, iPad, MacBook Pro, Macpro, Apple Watch and use all the Apple accessories. I have also been a fan of HUAWEI product phone and tablet. I store all my photos to Dropbox. Recently I upgrade my Dropbox program on my HUAWEI Matepad pro which I bought last month and I could not use it anymore. I used to share my photo through Dropbox app on it but after the upgrade it showed ‘Installation failed. The app dropbox is missing required components and must be reinstalled from an official store’ can you help me to correct this. I am always a big fan of Dropbox and love it because you can connect me to all the device that I have because I share a lot of photos. But now I can not use it on my HUAWEI Matepad pro. Which I used to do it. Please help.
