There are no RRE series at the moment.

Is there any plan to get RRE back on SRS?

It doesnt seem likely that there will be any new r3e races here unless some youtuber hosts it.
Last r3 season was mid april to late may and nothing since then, so you are probably better of looking for r3e races in the browser ranked/unranked or find a league on sites like raceapp.eu or others to find something that works for your timezone.
