Potty Training Exasperation

I have a 7 month old Morkie who I have had for about two and a half months. I have done my best to be consistent with potty training, taking him out every hour and 10/15 min after eating and playing. He will go potty outside consistently but still will have accidents inside. It’s getting less frequent than at the beginning but I see a lot of posts of how they should be almost fully potty trained at his age. I just feel like I’m failing and I don’t know what to do. Is it normal for him to still be having accidents? I’m trying to just stay the course with frequent trips and praise when going outside but I just don’t know!!!
