I am trying both Mlem and Wefwef at the moment, and even though I select the “subscribed” options for my main feed, the posts I see are different. It seems like WefWef shows me top posts from the day before and Mlem is more current? But I still haven’t figured it out.
Not singling you out, but speaking of bugs in the new stuff, be sure when you submit a post and it hangs a bit to not hit the button again before you check somehow if it went through. On mobile this may be a lot harder than on desktop, where you can just open the thread in a new tab and see if it took. Hopefully that process will be improved soon to not allow double entries and to give better feedback on if it went through. Even Reddit’s older system sucked at the feedback part with that 501 error or whatever.
