Hi! I think there is a bug with restoring values from the storage - if you saved the value into a storage, for example from a slider or switch, and then restore this value, then only the position of the thumb changes, but not the value. Accordingly, no functions are performed inside the slider block.
In Thunkable classic everything worked as expected
here is anapplication for example - https://x.thunkable.com/copy/aa75db1b58e2f01f25ba2c8b852b4cc7
