So here is my issue regarding iOS 26 Beta 3.
I was playing a game called BangBang Survivor, while inside the game there is an option to make the game ad free with a monthly subscription. Somehow i found that it doesnt work anymore on Beta 3. When I clicked renew subcription, it shows “This Purchase has already been bought. It will restored for free” and I found that buying diamonds actually working, except those ad free subscription was not working. I contacted game dev for this issue, they cant seems to solve anything and asked me to contact Apple Support. But Apple Support doesnt solve the issue as well and asked me to contact the game dev. I guess i will need to wait for next update to see whether this issue will finally solve or not.
