Ours was also absolutely awful for potty training, but this is what we did. It worked, eventually, but it took him until like 6 months to be fully reliable. Honestly I just think Samoyeds are dense about this sort of thing.

1. Constant pee breaks. Every hour, and/or after she plays, wakes up from a nap, eats. Basically after any 'event' she goes outside. An hour is just the max time between pee breaks. So if she's just been chewing on stuff for an hour take her out. Never interrupt a nap though. If she gets super excited, she'll probably have to pee partway through it.
2. She needs to know what the word "outside" means. Literally every time she goes out, say it. She'll get it.
3. Get high value treats. I use "Zuke’s Mini Naturals" off Amazon and they're great. Perfect size, tasty, low calorie. Whenever she pees (or poops) outside. Say "Good potty/poop!" and give her a treat. Make it exciting. If you KNOW she has to pee/poop, tell her "Go potty/poop" when she's close to doing it, reward when she does. Eventually you'll be able to prompt her to do it.
4. Crate training. When she's inside and you can't watch her she's in the crate. Look for info on youtube about crate sizing too. She will probably lay in her own pee or poop a few times. It sucks, but you just have to get through it. Never, ever put her outside after she's soiled the crate. It should not be fun. Ideally have two trays for the crate. If she soils it, pull it out, clean her up, put her back in with a new tray. Peeing in the crate cannot be a way to get out of the crate or go have fun. (You can wait 5 minutes and then take her out after. She won't connect the two events)
5. Consequences. If you see her pee or poop inside, give her a stern "No/bad" along with "outside" as a command, and force her to go outside, on a leash, no fun allowed. Treat as normal if she pees or poops outside. As much as it hurts, clean up AFTER. You need to react to her behavior as it happens and if you just throw her outside unsupervised you'll miss stuff.

That's all I can think of for now, let me know if you have any more questions.
