I think this might be two separate bug which makes a bug four times harder to debug because they might confound each other.
This is unlikely to be an issue with the server. The server is pretty robust. If you see a server issue with radar, you should see the same with other data sources.
I have noticed sometimes the processing does not process a certain time, i.e., is can appear blank. I’m not sure where this problem originates.
Flowx automatically checks for new data every 200 seconds if radar is turned on, otherwise it checks for new data every 15 minutes. I’ve just checked and this is working.
There might be a bug that when you reopen the app, it doesn’t check for new data. I’ll look into this.
Unfortunately, I don’t have radar where I live so I don’t use it daily. I need to adopt a place and use it more often to see these issues. I’ll try to do this. I need to find something interesting to look at like a hurricane.
