There is a serious issue with the mobile web version.
When reviewing saved sentence lists for study, even a very slight finger movement triggers a swipe to the adjacent tab. The swipe sensitivity is excessively high. Moreover, when I return to the original tab I was studying on, the page is always refreshed and reset to the first page, even if I was previously on, for example, the tenth page.
This makes studying on the mobile web extremely inconvenient. I strongly request that the swipe sensitivity be reduced.
