Help! 8.5m old baby on nursing strike!

My 8.5m old baby has been on nursing strike for 3 days and I can’t seem to get her to latch back on. She’s fully nursed since 4m old and refuses to take the bottle since. We tried feeding by the cup but the moment she tasted milk she refuses the cup. The only way we can get her to drink some EBM is to mix it in with her baby cereal. Any advice to get her to latch back on would be greatly appreciated! Desperate mum here 😩
