No, Weetabix have changed the recipe, not SW changing the syns. Stuff like this contains no free food so will ALWAYS be 1 syn per 20 calories. If you check the website you will see they are now 78 calories each - that is the reason they are now 4 syns.
Yeah thats what I meant by SW changed the syn values, thats what happens when i rush type I didn't know what had changed with the product, didn't look People changing recipes, so annoying, do they know it affects our daily syn intakes haha
