Hi @twister ,
Based on the information you provided, I think you should pay attention to below two things:
1. Do not use “&hidenavbar” in your syntax. The correct deep link URL looks like below:
https://web.powerapps.com/apps/{appId}?{query}
To get the appId, you should go to the 'Details' page:
2. As mentioned above, we should use ? symbol before query parameter. So replace your & symbol with a question mark ? symbol.
So you should use formula like this:
<a href='https://web.powerapps.com/apps/99b6b27f-a1e4-436e-8c87-a4788a4590cf?AppID=" & varRecord.ID& "'> Link </a>"
Check my result:

Best regards,
Allen

Hi @twister ,
Seems that you have not configured the auto navigate function.
So, please insert a timer control in the home screen, and add the following to the 'OnTimerEnd' property:
If(Not(IsBlank(Param("AppID"))),Navigate(DetailScreen, Cover,{Record:LookUp(sinc_main, ID= Value(Param("varAppID.ID")))}))
You can also set the 'Duration' property to a shorter duration say 600ms, 'AutoStart' to true and the 'Visible' property of the Timer to false.
One more thing, set Items property of the form in DetailedScreen to below:
If(Not(IsBlank(Param("AppID"))),Record,Gallery.Selected)
Reference:

Best regards,
Allen

Hi @twister ,
Try this to the Timer's 'OnTimerEnd' property:
If(Not(IsBlank(Param("AppID"))),Navigate(DetailScreen, Cover,{Record:LookUp(sinc_main, ID= Value(Param("varAppID")))}))
Best regards,
Allen

@twister ,

I have a thought you might go this way (which is what I do on all my deep-linked apps navigating to a record).

App OnStart

If( !IsBlank(Param("AppID")), Set(varID,Value(Param("AppID"))), Navigate(DetailScreen, Cover) )

Item of the Form you are going to

LookUp( SPListName, ID=varID )

then if you are navigating also from a Gallery - OnSelect

Set(varID,ThisItem.ID); Navigate(DetailScreen,Cover)

Please click Accept as solution if my post helped you solve your issue. This will help others find it more readily. It also closes the item. If the content was useful in other ways, please consider giving it Thumbs Up.

@twister ,

There is something else wrong here - I use that exact syntax on a number of apps and it is pretty simple - you are simply setting a Numeric Variable (varID) to the value of the incoming parameter and then using that to Lookup the matching record in the list. As you are getting no errors, all the code and names are correct - the only thing left is your incoming parameter. Put a label on the screen with varID and see if it is populated when you open the app.

Also get rid of the single quote as below
