I just tried and it work for me.
Sometimes, there are issues with the “tokenizer”, whatever that is. In that case go to the settings (the gear top right), then network and activate the 3rd item from the bottom, which might be called in English “Own account seeder”. The URL below will then be activated and that account is used as “tokenizer”. This helped me a couple of times in the past.
After using Aurora, don’t forget to sign-out. I think the numbers of log-ins is limited and there might be no auto-sign-out.
Preference should always be on free software, such as from F-Droid. But I also have to use some Guhgel Apps, even though most developers wrote me they were considering providing a download link on their web-page. For some reason, they never did.
By the way, Yalp does not work any more, nor the next generation of that. I think Guhgel inhibts their access.
