losing all recording midway through lecture

The recording screen froze midway through my lecture and stopped recording, as it was completely unresponsive (inc. the pause recording button and talk to AI chat box) I had to reload the page but after reloading all recording and conversations originally recorded completely disappeared and it went back to 0:00. There is no record at all of anything I’ve just learnt or got AI to summarise. Please check if there is a bug causing this freeze around 16min into recording and also is it possible to retain the information saved prior to reloading instead of it being cleared completely when reloaded.
