Astell & Kern E180 - Error APK

[quantx]

On my AK180, after updating to Version 8.3 of Qobuz APK, Qobuz Discovery generate Error 404. I still have my library in local.
I tried to revert to former version that worked flawlessly (7.15), but each time I get error of analysis blah-blah.
A pain in the ***

Can you disable it like on a phone? Doing that on Android reverts it back to the stock original version, which would do the trick.

Apart initialising, I don't see. And it will erase all content, which I won't be able to reinstall from Qobuz as per problem #1
