Ubuntu 19.10 here, all last RC, current one 7.5.0-rc5, have the same behaviour:
discovering, searching, downloading and uploading torrents work fine. But, the node is not used as a transfer node or as a exit node.( just 11.5G in weeks). Tested on diferent networks, without restrictions, gibabit connections.
With older versions, even in a complicated network enviroment, it did not alwasy work, bun when it did, i cold expect 30-50G/day.
Any hints, ideas…?
