Episode 13, which fulfills ABC's initial order, finished filming last night / early this morning. Warner Bros. probably will release all thirteen episodes eventually on one of the streaming sites. It was idiotic of WB not to put the show on iTunes; that may have helped to increase awareness.
According to Deadline and a few other Hollywood media sites, ABC stated that episode 7 will air on Tuesday, November 11, but airings of subsequent episodes are undetermined. My guess is that if next Tuesday's ep garners a 0.9+ in the 18-49 demo, ABC will air two more episodes. Holiday specials will be airing on Tuesdays in December, so do not expect to see the final four filmed episodes aired on ABC.
The double ratings of 0.9 this Tuesday certainly put the final nail in the SELFIE coffin. The cast and showrunner were live tweeting the episodes in a last-ditch effort to save the series, but alas, the election coverage did not help.
