I would expect update on Tuesday, since a "ftx week" starts on Wednesday [new offers, new raids and a global offer all announced on Wednesday]. But it is also possible that update will be released to Google Playstore/Apple on Monday so that they could extra time to fix the bugs... I also seems to remember that 1.21 and I think 1.22 version updates were both released on tuesdays.
It takes almost a day to publish an update for any apple I* junk.
