More details. I was able to have the stock PHONE app added to my Flip5 cover screen. It disappeared. It is not longer showing in the GoodLock/MultiStar/I ♡ Galaxy Foldable/Launcher Widget available Apps.
I have deleted GoodLock and MultiStar, reinstalled. I have reset the phone to factory and restored from Smart Switch made last week (before this issue)
Ah alright! So sorry for missing the finer details in your original post! I completely misunderstood. 😅 Given the steps you've already taken to get this resolved, this sounds like it might be a bug with the MultiStar app itself. You can submit this as Error report in the Members app's Support tab so that the Good Lock devs can investigate this, and maybe even offer a solution/issue an imminent update.
