Weekly Issue #33 - Part 2

Mobile Developers Cafe's weekly newsletter
Hello Folks,
Hope everyone is doing good and staying safe. The covid19 waves are rising again throughout the world. Do your best to stay safe, and if you are traveling, please follow the local pandemic regulations. If you are eligible to get the booster shots, please do get them.
Wondering why there is a Part 2? When we moved our newsletter from Substack to Rev, one of the issues persists problem of transferring. So the numbering is not in the right order(Week 33 is marked as #32 in Revue). So we are kind of hacking the title to make sure, the next issue’s title number is the same as the issue count.
Drink lots of water, stay hydrated and Happy Coding.
