faced the same issue, i have redirected my old domain spotifymod.com to new domain spotypremium.com on Nov 20, and till 24 everything was going very well, even i see some increase in traffic, new redirected domain was showing on some new keywords as the domain name also have some volume.
I have redirected following all the guidelines according to https://developers.google.com/search/docs/crawling-indexing/site-move-with-url-changes
But i have checked today and some of my keywords are totally vaniched from serp, there are no results of some pages even in top 200 results. The pages which was gaining more traffic are
https://spotifymod.com/spotify-vanced-apk/
https://spotifymod.com/spotify-downloader-apk/
https://spotifymod.com/download-spotify-plus/
which was ranked on 2 or 3 before i have switched domain. Now i want to know what i can do, till now i have created new social media accounts for the new domain, domain was fresh i have registered it 1 month ago,
I am trying to reach out to webmaster to ask them to change teh link towards new domain,
But i am getting some video out of the viewport errors for new domain on google search console, while domain is still moving in search console and according to google do not change content for 2,3 weeks.
Some pages are still intact in search now i am confused.
