So… that’s all of my apps updated now.
One of my apps took 10 days (7 working days) - I spoke to google and they said 7 working days is the average time for an update to go live at the moment.
My other three apps - took 14 days (10 working days). I sent the google contact another message yesterday about my remaining apps, then they were updated this morning. So that’s maybe worth a try if you’re waiting as long as I had been.
To reiterate: it took about 4 hours for the 4 iOS ones to update 🙄 oh well, at least they’re done now!
