Probably not relevant to whether or not the software has issues. What matters most is that the design is thought through (which can be easier from a non-office setting), that the testing is also thought out and done properly, and that pressure to release too early is resisted. Here, the software was presumably not tested for battery drain in this scenario (which suggests desk use/non-mobile devices). If developers/testers were commuting or working from coffee shops, it might have shown up earlier as a side effect, but otherwise it would need to be explicitly included in the testing plan (whether on campus or remote). Hopefully, Apple has changed this.
One effect of covid where I am has been that we are losing people from the team at very short notice and at higher rates than usual. Working remotely helps (staff may not be well enough to come in to the office, but can sometimes still work remotely), but we are still needing to continually replan/cover. That can be very disruptive to delivery. I imagine Apple is also suffering from this.
