Mobil Full Synthetic in 0W-20 and 5W-30 will be receiving GM Dexos1 approvals. With the current COVID-19 situation, approvals are slow coming as the testing labs are not considered "essential." So it appears Dexos 1 approval is just delayed due to the backlog at testing/certification labs. General Motors recommends the use of dexos™ approved engine oils for global factory and service fill in spark ignited and diesel engines. Importantly, the number of brands with dexos approved licenses varies over time. The list of Licensed dexos® brands is updated quarterly, with the most recent update on December 16, 2020.

Mobil 1 IS Dexos1 approved. Look at the label. I have indicated it with red in the picture below. To maintain your warranty without any questions or hassles, you MUST use a Dexos1-approved 5W30 oil (other than while on the track and switching to 15W50 oil).
I have been using Mobil 1 Extended Performance 5w-20 oil since I got the car in 2015 since it was Dexos -1 certified. I no longer see the Dexos-1 license on the bottles of this oil and Mobil 1's website no longer shows 5w-20 as certified Dexos-1 though 0w-20 and 5w-30 remain certified.
Applications Mobil 1™ 5W-30 is recommended by ExxonMobil for all types of modern gasoline-powered vehicles, including high-performance turbocharged, supercharged, multi-valve fuel injected engines found in passenger cars, SUVs, light vans and light trucks.
