wait for GSTR 2 period to be over i.e. 30th of november. After that view your GSTR 1A, if your receiver has already uploaded invoices, Accept it as per your record otherwise, reject them.
when it was not possible to file gstr2 for one month how can you think that it is possible to file for 9 months together. basically it looks that idea of invoice matching has been dropped by govt. due to system failure. Rest future will tell what they are upto.
