 ## Hero Animation won't work (after hot reload)
 
 That's a known issue. Hot reload won't refresh the module sets the hero cache. Refresh the whole page and it should work.
+
+## The components don't react to the change as I setting the store, until the page reloaded
+
+The `WritableAtom<unknwon>.set` might do an equals check. You must set a different object to ensure the atom sending a notify.
+
+The code below may not notify the change:
+
+```ts
+export function updateAcctInf(idx: number) {
+  const o = $accounts.get();
+  // ...
+  o[idx].inf = inf;
+  $accounts.set(o);
+}
+```
+
+Instead, set a new object:
+
+```ts
+export function updateAcctInf(idx: number) {
+  const o = $accounts.get();
+  // ...
+  o[idx] = Object.assign({}, o[idx], { inf });
+  $accounts.set(Array.from(o));
+}
+```
+
+Ja, the code is weird, but that's the best we know. Anyway, you need new object on the path of your changed value.
