Questions

hi,
When I’m on a second page and want to go back to the previous page, sometimes it gets something on the screen that does not allow me to run any action and it locked the page and I have to get out of the program, so what do i have to do with this problem?

i’m using F7 3 + Vue.

There could be some issue with router, likely produced by some error in your code, that blocks router. Would be good to see live example if you have, or more complete code examples
