OH 4.3.2 issue with showing trendlines in items in Main UI

The problem

The problem
I updated today my three PI systems from OH 4.2.1 to OH 4.2.2.
From now on, trendline from the icons under basic UI works in this way, that only a
black screen comes up, and not more the graph from the item.

This happens only under iOS devices in different browser or the native client app for iOS.
So simelar issue as with the graph summery but this time with trendlines from items values.

It can be fixed with reload the app in the main section.

Please have a look why this happenes…

The error is confirmed here:

Please see here: All happens only iOS based device. e.g. iPad. in Browser and aso in the OH App. Not on Windows based browser etc.

See my startscreen:

When I click on the Icon " Außentemperatur"

This windows comes up:

When I then go the main section from OH iteself, and click the "reload the application button", go back and click the
Icon once more it looks like it should:

Expected behavior

Please see here: All happens only iOS based device. e.g. iPad. in Browser and aso in the OH App. Not on Windows based browser etc.

So, does that only happens once after installing OH and then it works ? If that is the case I would bet that this is somewhere a caching problem but I wonder what the effort would be to track down or isolate the root case. This is in particular hard on an IOS device as you IMHO need special debug setup to check what is happening within the embedded browser and then reproduce it. Even though this might my confusing in the beginning I am not sure if someone would fine the time to investigate this further (just trying to set expectations here) or do you think that this is a critical bug?

Hello Some more information to that: It happens with:

The Issue exist on three different machines with the same setup with a RPI4 and 5 after the update from 4.2.2 - 4.3.2 now
The issue been seen 1/2 year ago with the same symptom.

It is on all the time there also after serverall time reboot the whole machine OH installation and also the client.

It happens on my ipad 12 with iOS 17.
With latest version of Safari, Firefox, Chrome Browsers and the native OH Client.

It will NOT happen on my iPhone with 18.1.1 on any Windows machine and Android phones at home.

So far all cleaning of cache from the browsers have not been solving the issue.

As no one have this days the issue, or have also reported, that they have seen this, ist seems it is not the critical.
The graph will be shown, after one click more to (Steuerungselemente) botton.

So feel free, to check what was the last time changed in this area, that the error is back again.
