The AvioPortolana for example with 800 MB downloaded once in 2 or 3 minutes, now it takes nearly 30 minutes. Observed on Mac, iPad and iPhone, all with the latest Skydemon version.

Perhaps you were trying to download it at a time of high contention, for example on an AIRAC day when there will be thousands of people all trying to do the same thing.

If I switch to cellular it works fine. Tried with Windows, Android and iOS. My ISP is Telekom and I have a feeling that it has to do with them. If I set up a hotspot with my phone and connect to it with my tablet, it is fast. If I connect to WiFi with Telekom ISP it is super slow. Tried at 3 different locations (unfortunately all Telekom ISP) with the same result. Browsing, downloading anything else, etc. is fast. It is just SkyDemon where I experience the issues. Any suggestions how I can resolve this?
