Reproduction steps

Account type: Local
Reproduction steps:
Install Read You 0.16.1 on Android.
Add the official Deutschlandfunk RSS feed: https://www.deutschlandfunk.de/nachrichten-100.rss⁠
Keep the default sync interval (30 minutes).
Open multiple Deutschlandfunk articles from the feed over time.
Occasionally, opening an article results in an Akamai WAF error: Access Denied Reference #...
This issue is intermittent and cannot be reproduced on demand.
The Deutschlandfunk technical team investigated one of the reference IDs and confirmed that the request was temporarily blocked by their Web Application Firewall due to an "IP Burst" (too many requests from one IP). They suggested that the app or one of its libraries might generate more HTTP requests than expected.

Crash report

Not applicable — the app did not crash.

Start by reproducing the Deutschlandfunk RSS scenario described for Read You 0.16.1, focusing on sync and article-opening request activity and comparing it with the reported Akamai IP Burst block. The issue names no source file or test; done means identifying and preventing the excessive requests, with coverage for the request behavior.
