I updated my iPhone 7+, iPad mini 5 and iPhone 13 mini this morning and I can't sync them with 13.2.1. I didn't update my Studio because of a bug with a third-party vendor on 13.3 but I have a workaround for that now (I'm using an extra M1 mini to run the program) but it's annoying that you have to be on the latest version to be able to sync mobile devices. In general, sometimes you have to be on the latest version and sometimes you don't. I was hoping to go for a run after syncing podcasts but I have to update now and then sync and then go out running. The update takes some time and sometimes that isn't convenient. I guess I should have updated my podcasts before updating the mobile devices.
