I also have the same problem. There is workaround - application waits some time and makes another attempt to get the data from server.

Here is mockup (this is Flutter/dart):

   Widget build(BuildContext context) {
    ...
    loadData();
    ...
    //building th UI with data from items list
    ...
   }


    loadData() async {        
        //is not loaded but there is internet connection
        if (!isLoaded&&isConnected) {
          try {
              querySnapshot = await query.getDocuments(source: Source.server);
            } 
            catch (ex) {
              print(ex);
              Future.delayed(Duration(seconds: 10), () {
              // setState to trigger build 10 seconds later to make one more attempt
                  setState(() {
                      isLoaded = false;
                  });
              });
          return;
        }
    // here goes the code to handle the result 
    items =  querySnapshot.documents.map((s) => Course.fromDb(s)).toList();
    }
