I have rebuilt the caches, but as this seems localised to a small number of members, it would help if you could post screenshots of your account setttings (
https://www.cyclechat.net/account/preferences), specifically:
- Content options
- Push notifications
- and the Alert Preferences section
I have also installed a new add-on
Persistent Alerts. The default software behaviour is not to alert again if you don't revisit the thread. This should help with that, but you need to enable it on your account.
Go to ...
https://www.cyclechat.net/account/preferences#alerts ... and enable
Generate new alerts without reading threads and then click the
Save button at the bottom to enable it on your account.
Let me know if this helps.
