SD card question please help

How far back can I use the playback with a 32 GB sd card & how long with a 128 GB sd card ? Is that considered continues recording ??

This article should help. Although Wyze doesn’t recommend anything over 32GB, people have used them without many problems. For those cards, simply divide by 32 (128/32=4), and use that as a multiplier on their 32GB numbers.
