I am not totally sure, if things are as good as previously, but there is a major quality difference on my side. I also did a total reset of my printer and filament settings, so it is a bit tough to pinpoint the exact cause of improvement.
You can easily change to firmware versions up and down using the Smartphone App, so I still recommend you to try to give it a shot.
I really don’t think changing underlying settings like infill/wall overlap is the way to go forward to improve the expected quality for the basic samples prints. They should (and have been in the past) come out beautifully with standard settings on the A1. I also do not see any bed adhesion issues from the photos in your post.
