Whether both designated partners of an LLP should sign the financials?

In this particular LLP firm there are 2 designated partners. One of them is NRI. Due to Covid pandemic and other reasons the NRI is not in a position to return to India. Hence he is unable to sign the financials along with the other designated partner. Now in LLP Act, 2008 as well as related rules and the LLP deed of this firm it mentions the designated partners shall sign the financial statements and manage the affairs of the LLP. Its unclear to me whether all of the designated partners of an LLP should sign the financials. So Doubts are.... 1) Is their a minimum for the no of designated partners to sign the financials? 2) If both the designated partners has to sign, can the NRI assign a third person to sign on his behalf? 3) Is their any special reliefs in this regard for this particular financial year? [NOTE-1:- The NRI designated partner is the person who actually manages the business affairs of the LLP. But this won't affect the importance of which of them to sign if only one designated partner has to sign. Right??] [NOTE-2:- If all the designated partners have to sign as per law then what if the LLP has 3 more NRI partners at different countries. Still all have to arrive in India and sign?? In the LLP Act, 2008 its mentioned at-least one of the designated partners must be resident in India. Was it purposefully mentioned for the sign requirements in such a grave situation, so that at-least one designated partner can sign??]
