Refresh browser/App onstart

[JimboSey]

Hi,

Got a frustrating issue that when I publish an update to the App, some users get an older version, when they refresh brower is pull through the latest version.

Anyone had this issue and know a quick solution? For example is there something to put in the OnStart so that it would refresh browser/app?

Thanks in advance.

Hi @JimboSey ,

You could put the current version number in a reference list and then have the number hard-coded at app OnStart -  do a LookUp and if the numbers don't match, put up a message for them to exit and refresh until they do match.

I agree with @WarrenBelz, and I do this for all of my Apps - it's also nice to have a condition where if the lookup = "Under Maintenance" then take the user to an under maintenance screen/message so that they don't interact with data - its really useful when you need to do backend data work but can't have users playing with data while you do

Hi, thanks for your reply.

Could you break this down a little for a PowerApps novice please?

If any help, my data scources are mainly SP lists. 

How would I hardcode in the onStart?

And, the list reference just be a single line text column in an SP list?

Thanks again

Hi @JimboSey ,

Have a reference list (they are very useful for many reasons)  with one record - I will call the field Version here.

App OnStart

If(
   First(ReferenceList).Version <> YourHardCodedVersion,
   Notify("Not current version - please exit and refresh", Error)
)

Hi,

I have tried this, so created a single line of text column in my SP list, the column name is 'VersionRef'. I've put a number 1 in the first row of this column.

My code on the OnStart is as you suggest as below but changed ReferenceList to the name of my list, changed .Version to .VersionRef and replaced YourHardCodeVersion just with the number 1 (so matches what in my SP list).

But it seems to show the error, regardless 

Any help appreciated, thanks.

If(
   First(ReferenceList).Version <> YourHardCodedVersion,
   Notify("Not current version - please exit and refresh", Error)
)

Hi @JimboSey ,

You really should make a separate list here and it certainly should work (it is the simplest of filters), however if you put First(YourListName).VersionRef on a label, do you see the number you are after and is your column numeric or Text ?
