Hi Yannick ( @ysc ), sorry for bothering you. I’d like to bring this problem to your attention: When launching MainUI as PWA after a while the client gets disconnected from the server. I have seen this problem rarely on older OH3 versions and have this problem with OH3.2 ~10 times a day. This pro…

Looks like a SSE connection problem. When that happens go to Developer Tools, Debug (the 2nd tab at the top), click Stream Events and check that you have events coming in. (Change some items with another device if necessary). If you have problems, and if it’s specific to iOS Safari, then you might…

Hi Yannick, I think I found the culprit. After a while the browser makes a call to this website: safebrowsing.googleapis.com after that app.js is not “connected” anymore [image] the browser lost all items’ states: [image]

I did some more testing: neither disabling “Fraudulent Website Warning” in Safari settings nor disabling internet access on the router solved the problem. I guess it is simply the fact that the browser does an API call (safebrwosing API) which stops the connection to APP.JS no matter if the API call…

[image] Oliver2: [image] image926×1044 88.4 KB Is this remote debugging on your iPad, it looks like Chrome’s dev tools? Anyways there are a number of scripts that aren’t related to the UI - basically everything above app.js on that screenshot, and the last “threatListU…”. Maybe that’s norm…

Hi Yannik, yes, I used the link you provided above. the screenshot is taken from there (it starts a virtual iOS device embedded within inspection tools which look like chrome dev tools). The last entry you see and what you mentioned (threatListU…) is exactly what causes the problem. I saw it with …

ah ok, you used the BrowerStack cloud service itself, not your actual iPad. I was confused because I didn’t know Safari used Google’s Safe Browsing API. [image] Oliver2: EDIT: at the same time, the blue bar next to app.js disappeared That’s weird because app.js is the main script that shoul…

[image] ysc: maybe you can try disabling Safe Browsing I already did: [image] Oliver2: neither disabling “Fraudulent Website Warning” in Safari settings nor disabling internet access on the router solved the problem [image] ysc: I didn’t know Safari used Google’s Safe Browsing API…

Another proof is the following: When using iOS App (Beta version which supports MainUI) then there are no problems at all. However, the app is not capable of showing oh-popups

[image] Oliver2: However, the app is not capable of showing oh-popups Do you mean popups in widgets ? Those are working over here, no issue with that.

sorry - let me be more precise. Within that popup there is a webframe which shows my video camera (mjpeg format). The popup appears but there is no video. I guess that the iOS app does not support javascript which is required to refresh video images.
