This popup was recently introduced in PR-2174.
I don't know exactly why, but voyager prompting me that I'm about to lose my progress was sort of strange to me in the context of scrolling on lemmy.
I understand why someone wants such a feature, but IMO this should be turned off by default and available as an option.
I'm not sure what the expected outcome is here. No Lemmy client I'm aware of is capable of keeping your progress if you leave the feed.
If you don't want to leave the feed, hit cancel. If you do, hit leave. If you like being surprised by losing your place (or you just don't care), check the box and tap "leave."
The ideal would be for you to be able to come back to your place, but that feature isn't implemented yet, server level.
Sync seems to? Unless im misunderstanding here. But I can close it come back like 6 hours later and it will still be where I was. Obviously if I do any additional scrolling since the order of the feed has changed it won't be able to give me the feed as it was but it does at least remember the last page of things I was looking at
I personally think this popup is not a great UX, and the text ("lose progress") is unspecific.
It would be smarter to be able to return to the last feed and position with a simple gesture. Or allowing an option to hide posts that were shown during the last visit.
My desired outcome for this thread is to get some feedback. Apparently, most people here like this change, so I am not going to do anything further.
One of the developers told me it's impossible to return to the last feed position. I don't know why, but, I'm not a programmer. I don't doubt it. It was possible with Reddit clients. Could be something Lemmy hasn't implemented, or hasn't implemented yet.
