Hello, and thank you for your question.
The slower loading times you experience with the meteogram are known and can be influenced by factors such as multimodel meteograms requiring more data, app cache issues, or device-specific app update effects. On iOS, timer logic can mark meteograms as updated even if data is old, requiring a manual refresh to load fresh data. Troubleshooting steps include fully closing and reopening the app, refreshing the meteogram preview, restarting the device, or reinstalling the app.
Developers are aware of caching and zoom-related performance issues and plan a new meteogram implementation in future updates to improve loading times. Temporary workarounds include using the website on a mobile browser or force-restarting the app. We hope we were able to answer your questions and wish you pleasant weather with meteoblue.
