An update can change how the app requests permissions like storage or network access, and the device does not always re-grant those automatically once the new version installs. The app then fails right at launch because it cannot access something it needs to run, which reads to you as a random crash rather than what it actually is: a permissions problem left over from the update. Checking the app's permission list in your device's settings and manually re-enabling anything that got toggled off during the update is the fastest way to confirm or rule this cause out entirely.

Updates sometimes reset local app data, including a saved playlist or login configuration that was working fine before, so the app opens correctly but is now pointing at nothing at all. This looks exactly like the subscription itself failed, but it is usually just a local settings wipe tied to the update process rather than anything server-side. Re-entering the login or playlist details directly answers the question fast, since the account itself is almost never the actual cause of a channel list that goes empty right after an update installs on the device.

Some updates change the default decode path the app uses, switching between software and hardware decoding without telling you, and the specific device processor you own may not sustain the new default smoothly the way it handled the old one. If the app itself is stable but playback specifically got worse right after updating, check for a playback or decoder setting inside the app's own menus and try reverting it back to the previous option, if the app happens to offer one at all, before assuming your connection itself got slower.

Sometimes an update introduces a genuine bug that no device-side setting can work around, since it is a flaw baked into the code itself, not a configuration problem sitting on your device. This happens periodically across apps of every kind and is worth naming honestly instead of repeating the same restart-and-reinstall cycle over and over with no result. Checking the app's changelog or support page for a known post-update issue, or rolling back to the prior version if the app store allows it, is the appropriate next step at that point.
