An odd issue with Tape It and low power mode since iOS 18

Hi,
I've been running into an odd issue with Tape it since iOS 18. I often will "tape" things when I'm in low power mode. I always keep my phone in low power mode. Up until iOS 18, I was able to successfuly make long tapes with tape it. Now, I press start recording, and I wait a few seconds, go ahead and lock the screen, and it only records for about a minute. It never used to do this before iOS 18, even in low power mode. Do you think this is something that could be fixed?
It doesn't seem to do this when I have a headset connected, or when I'm not in low power mode.
Thanks
