Hi
I found something "strange" :
I have simple list NameraneHodnoty with Column IDMeraca
I put simple timer with for example 5second duration and repeating
OnTimerStart is function
If(Connection.Connected,
Refresh(NameraneHodnoty);Revert(NameraneHodnoty);
Patch(NameraneHodnoty,{IDMeraca:9123})
)
- When App runs with internet, it works fine (putting new value into List)
- When App runs with internet, lost connection, get connection back, it works fine (like above)
- But - When app runs without internet, and then connection get back, on function Patch it is returningThe data source supplied to the function is invalid

I tried it without Refresh / Revert but same resut.
(from I tested .. when powerapps run without internet, and then connect to internet, when it try to Patch value)
I tried to retrieve datasourceinfo
but with no luck .. again same error messageIf(Connection.Connected,
DataSourceInfo(NameraneHodnoty, DataSourceInfo.DisplayName, "IDMeraca");
Patch(NameraneHodnoty,{IDMeraca:9123})
)
Usage is when user add new items, it added just to collection and SaveData. When connection get back data are automatically send to server even if app is closed.
Maybe I am doing something wrong, just i found this issue.
Please, is there some workaround. Thanks
