Filter list with "Diff-Path" but without "Diff-Expires:"

[Procyon-b]

I have 2 lists (2 adguard regional lists ; NL FR) that have a "Diff-Path" header without a "Diff-Expires:". uBO (1.58.1b10) handles them with no differential update: full 5 days update cycle. (I have only updated to b11 right now)

Should uBO use a default value for "Diff-Expires:" if there is only a "Diff-Path" header, or should adguard fix the headers in its lists ?

Hmm, it seems not only NL, FR, but all AdGuard lists in uBO lack "Diff-Expires:":

• AdGuard – Ads
• AdGuard – Mobile Ads
• AdGuard Tracking Protection
• AdGuard URL Tracking Protection
• AdGuard – Annoyances

Clock icon says they were updated several days ago.

AdGuard uses a different way to encode diff-expires, there is no code yet in uBO to deal with AdGuard's differential update approach.
