Yeah, the same problem. In PWA when navigation back, the page will freeze until click somewhere

Hello, guys ! I think, I have similar problem.
It happened only in ios system, when I sometimes started to navigate quickly, the app became frozen and not respond.

What would you recommend (what tool to use) to catch it and deal with it ?

I got It happened only in ios system too,
My case is swipe back parent> enter child view > swipe back .. > enter ... hangs
after hangs, back button is no longer response
