“This year will be the problem for those who only eat gebrokts the last day which is on shabbos, when will it be made?”
Not a problem, we will do the same thing we did 2019, 2018, 2015, 2012
We will make them on Friday, don’t forget an eruv Tavshailin*
(* No reason to say Hoil doesnt apply, many eat Gebrokts on shevii shel PEsach (as can be seen in this thread) kids can eat it, choleh shein bo sakana etc )
