Netgear MR1100 ATT still on old firmware

I looked all over this forum board for an answer, uyet found none. I sadly still have firmware version since last update, 1/24/20. Constant disconnect and battery issues many have mentioned. Will there ever be a ATT release to this issue so my unit can enjoy all the fun everyone else is having? Just wondering. Version installed at the moment 12.05.05.14. Like the other peole, cannot upload the file I have downloaded as there is no bottom area in firmware pare to add the file like in the manual update picture layout.
