Hmm, that's weird. How many subscriptions do you have? Works consistently for all my accounts, so not sure what could cause this. Please let me know if the issue persists!
I apologize for not replying earlier. I think I found the reason for this error. I will try to explain now.
TL;DR: I think the reason is incorrect processing of the status of subscriptions.
I test many apps: voyager, avelon, lemma, mlep, memmy, arctic, artemis, lemmios, gravity. lemma had a similar behavior with the subscription feed.
Some applications use the default settings when updating, including favorite in subscriptions.
In the process of using applications, I perform standard actions - reading, subscribing to new communities, rating, commenting, etc.
When avelon started to show an empty Home feed, but at the same time fully showed local feed and communities to which I was subscribed if opened by name, it caused so me questions.
So I started checking it in other apps, and here I discovered that they show different subscriptions.
After that I removed the "favorite" marks from my subscriptions in my apps. Then checked the list of subscriptions in the web version of lemmy.world.
Some subscriptions in the web version were displayed with the status "pending subscriptions". that was it! after removing these subscriptions, avalon immediately pulled up the list, and lemma showed the list after relogin.
Thank you - this is pretty much the best bug report ever. Are you a dev by any chance? :p
Didn't even know about the "pending" subscription type, I'm sure other lemmy app devs are also unaware. The lemmy api is not super well documented atm, so it requires a fair bit of poking around in the code to figure out how stuff works.
