If you clicked the download link for a GPX file, you will be asked whether the GPX file should be loaded (step A). If you use the default Safari browser on the iPhone, the file is stored in the download folder, which is made visible by the symbol in step B. Clicking the icon displays the downloaded file (step C).
Clicking on the file displays the rather cryptic GPX file in text format. By clicking on the forwarding symbol at the top right (step D) you will get to the dialog where you can choose which app you want to use to open the file. Possibly. "Viewranger" hides behind the "More" item (step E). When you arrive at "Copy to Viewranger" (step F), you are almost there! Then the Viewranger app should open, you have to confirm the import of the file there again (step G):
PS: If you send the GPX files to your smartphone as an e-mail attachment, you go into the process in step D. This works quite well for most Android smartphones (and of course slightly modified compared to the screenshots above).

Hello service, I wish the whole team a healthy and successful New Year and stay healthy. I have a request for you, I got a message from you to switch to Outdooractive because of the change. (Challenges). I'm sorry that I can no longer use the challenges with you. But I have no intention of switching. I remain loyal to you and I am also very satisfied with the app. Have a nice weekend, greetings from Bernd from Saxony

Hello Bernd,
could it be that something got mixed up? You've landed on the wanderndeluxe website and not on ViewRanger :) Still, it's interesting to know that ViewRanger is now being merged with Outdooractive. I'll have to think about which app I recommend soon...
Regards
Frank
