Hi. I have 2 part time jobs in 2 different offices. Recently I broke my knee and now I have to work from home. My team viewer has been suspected for commercial use (which is ok). I've read the support info and it's still not clear for me - how many licences do I have to buy? 1 (for my home pc) or 3 (1 for my home device + 1 for each office pc)? I will be connecting from my home pc to both office pcs, but not simultaneously, no other usage. Please help. Thanks.
