Flutterflow 4 and Sonoma/Safari - Using significant memory reloading pages?

Is anyone having any issues with pages that were previously working but are now reloading in Safari due to the page using significant memory?

I have a page with a pdf viewer - which was previously working fine, but since either flutterflow 4 or Sonoma (I can't tell which one as I installed at the same time) - I can no longer even work on this page as it keeps reloading due to significant memory use?

Please let me know if anyone else has come across this or if anyone has any suggestions - thanks in advance for anyone who responds!
