P: Lens Correction Profile for Canon RF24-240 exhibits edge artifacts.

When I import CR3 images both Lightroom Classic and Photoshop show hashed horizontal lines at the edges. They happen in the most colorful areas. Other software can open the images without the edge "hashing." 
I have read some older questions and tried turning off graphic card acceleration to no avail. Converting to DNG changes nothing. 
I ave attached a sample. 

@Jim Wilde , thanks for the tip! It's not ideal, but will work in a pinch in some cases. Still, it's not possible when you are offline, or have just imported 500 photos and have a lousy hotel wifi as your only connection. With a poor conneciton, the photos you want to fix may not be synced yet to the web. I think I will add this feature request.

Oh I didn't know there was a web version. I'll have a look into that. Thanks for the info 

Whilst it is not yet possible to change lens profiles using LrMobile on an iPad, have you thought about using the LrWeb app via Safari browser on the iPad? Lrweb does allow lens profiles to be changed.

Yes I have the same issue with lightroom mobile on the ipad ....can't see any way to change the lens profile.

Does anyone know when this will be resolved as most of my work is with the 24-240 lens

I know how to change to the older profile in Lightroom Classic and in Camera Raw. Is there any way to do this in Lightroom Mobile? On my iPad, there seems to be only a switch to enable or disable lens corrections. That's an aggravation when I'm on the road with just my iPad for editing. 

ACR is enlarging the C CR3 file by approximately 120 pixels on all sides. The expanded space is filled by taking the border pixel and using it in the expanded space. The attached _A9A2508.jpg was exported from lightroom as jpg becasue I caqn't upload the CR3 file.  The problem is most obvious on the bottom and right side but does exist on all sides on close inspection.   The sreenshot is from PS.  Current versions of PS LRC and ACR and "up to date" in Adobe Creative Cloud. I got error "

• The attachment's _a9a2508.cr3 content type (application/octet-stream) does not match its file extension and has been removed." when I tried to include the raw file.

I too have seen this problem - EOS R + RF 24-240 lens but only after the August 2021 update. It's not just in LrC but also in PS when processing a raw file using CameraRaw. Initially contacting the online help chat, the agent said that they could only see one profile listed for that lens and it didn't have the v2 suffix. They advised me to look in the CameraRaw LensProfiles folder and I told them that two profiles were there. I don't think I was believed.
The workaround is easy to do.

I am shooting pics with Canon R5 in RAW, Canon R24-240 zoom in this example. After uploading the files into Lightroom, it seems the edge of each picture distorts. Is it something I am causing, or is this normal? It is happening on all 4 edges. I do not noticed this edge problem when reviewing the pics on the camera. Adobe Photoshop Lightroom version 4.4 on Dell Windows computer running Windows 10 Pro version 1903. I have been cropping the pics to eliminate, but just seems odd.

When I open many CR3 files created by my Canon R5 using ACR 13.4 they exhibit the fringe aberration around the edges shown in the following screen capture. When I open the same CR3 file in Canon's Digital Photo Profession 4 the aberration does not appear as shown in the second screen capture. I know another person with the same problem. This also happens when importing some CR3 files into Lightroom. I can provide sample CR3 files if you wish. Thanks.
