Even though Apple has reopened its retail stores in China, many of its supply chain operations are still in flux. A new report from Bloomberg details some of those struggles, but says the 5G iPhone 12 is still on track for this fall.

Citing anonymous sources, the report explains that as of right now, the next flagship iPhones with 5G capabilities are “still on schedule to launch in the fall.” Mass production, however, isn’t slated to begin until May, so delays could still materialize once that process begins.

Even though the iPhone 12 is on track, one source told Bloomberg that Apple’s supply chain is still not moving at its normal pace due to a slow down in component shipments:

For example, key Apple suppliers in Malaysia have halted production due to a two-week lockdown in the country because of COVID-19. Apple suppliers and teams in other countries, including South Korea, the UK, United States, Italy, and Germany have also been affected.

But despite many of these constraints, Apple was able to build test versions of the iPhone 12 last month:

Apple finalizes the majority of design features for new iPhones between November and December of the year prior to launch, the people said. It begins mass-producing new casings around April and then starts a late manufacturing stage called Final Assembly, Test and Pack in about May.
