There's no need to update your invoices to allow partial payments, Ana.
Since you mentioned that your client is no longer able to make a partial payment, could you please clarify if they are encountering any error messages while attempting to do so? It would be helpful to know what is preventing them from completing the process so that I can provide a more targeted solution.
In the meantime, let your client clear their browser's cache to eliminate excessive data buildup that affects the platform's performance. After this, have them try making a partial payment again. If the issue persists, they can use other supported browsers.
Comment below if you have additional questions.
