On the MySilla Prism every time the Prism page is refreshed it goes from offline to online. What can I verify?
Do not use Safari, Samsung Browser or other vendor browsers (such as Huawei Browser).
Uninstall PWA (if you have it installed) and clear the cache from your browser and site cookies.
Check that there are no extensions installed on your browser (such as AdBlock for example).
Log in by connecting to a Wi-Fi (certainly more stable than the GSM network) and do not use the phone’s data network.
It is correct that you initially see the status “offline” and then “waiting for reception.” After a few seconds (depending on signal speed) you should still see the “online” status.
The problem may be due to the instability of your Internet line.
From a PC you could try using a lighter browser such as Firefox.
From mobile it could be that there are many applications installed that go to slow down the operation of the device.
It could also depend on the speed of the processor (have you tried checking the speed of the connection via Speed Test?).
